Standard x-ray powder diffraction patterns are presented for 58 substances. These experimental patterns, useful for identification, were obtained by diffrac- tometer methods. The lattice constants were refined by least-squares methods, and reflections were assigned Miller indices consistent with space group extinctions. Relative intensities, calculated densities, literature references, and other rele vant data are included.

Key words: Crystal structure; densities; lattice constants; powder patterns; reference intensities; standard; x-ray diffraction.

INTRODUCTION

The Powder Diffraction File (PDF) is a con tinuing compilation of diffraction patterns gathered from many sources. Produced and published by the JCPDS International Centre for Diffraction Data, 1 the PDF is used for identification of crystalline materials by matching d-spacings and diffraction intensity measurements. Under the partial spon sorship of the JCPDS, the program at the National Bureau of Standards contributes new or improved data to the PDF. Our work also aids in the de velopment of diffraction techniques. This report presents information for 58 experimental patterns, and is the twenty-eighth of the series of Standard X-ray Diffraction Powder Patterns. 2

Appropriate annealing or recrystallization of the samples improved the quality of many of the pat terns. A check of phase purity was provided by indexing the x-ray pattern and by optical exami nation.

Optical data. When reported, optical mea surements were made by grain immersion methods, in white light, using oils standardized in sodium light, in the refractive index range 1.49 to 2.1 [Hartshorne and Stuart, 1970].

The names of the sample colors are selected from the ISCC-NBS Centroid Color Charts [1965].

Interplanar spacings. All spacing determi nations were made using an internal standard mixed with the sample, packed in a shallow holder. Choice of the standard was determined by the need for low angle and unobstructed reflections. The amount of standard was estimated so that the in tensity of its strongest peak would be about equal to the intensity of the strongest peak of the sam ple. The internal standards used were of high purity (99.99%). The lattice constants used for them at 25 C are given in Table 1; the 26 angles were computed using cell dimensions uncorrected for index of refraction.

The internal standard Si powder is available as Standard Reference Material 640 [1974]. The lattice constant for the Si was refined from mul tiple powder data measurements made with tung sten as an internal standard [Swanson et al., 1966]. Single crystal cell parameter data were also collected. The lattice parameters from the two methods agreed within three parts in 10s [Hubbard et al., 1975]. D-spacing results using SRM 640 will be in agreement with patterns re corded in this series of Monographs since 1966.

All patterns were recorded at 25 i 1 C on a diffractometer equipped with a focusing graphite or

Page 8: NBS25-18

lithium fluoride crystal monochromator located between the sample and the scintillation counter. Pulse height discrimination was used as well. All data were collected using copper radiation: \(CuKofj, peak) = 1.5405981 [Deslattes and Henins, 1973].

The readings of 26 were taken at positions about 20% of the way down from the top, and in the center of the peak width. This avoided errors associated with aberrations at the very top of the peaks. The Kor2 peaks were occasionally read to assist in establishing a Kc^ peak position, but Ka2 peaks are not reported.

At low angles, Kofj and Ka2 peaks were unre solved for both the sample and the internal stan dard. The internal standard corrections were established from the theoretical values for Kc^ and were applied to the unresolved low angle peaks, as well as to the resolved Kofj peaks in the higher angle regions. In general, if the internal stan dard correction varied along the length of the pattern, linear interpolations were used.

Structure, lattice constants. The space group symbols are given the short Hermann-Mauguin notation. Also given are the space group numbers listed in the International Tables for X-ray Crystallography, Vol. I [1965~T

Orthorhombic cell dimensions are arranged ac cording to the Dana convention b>a>c [Palache et al., 1944]. Monoclinic and triclinic lattice con stants are transformed if necessary in order to follow the convention of Crystal Data [1973]. The lattice constant ratios, a/b, c/b, and c/a, also follow the conventions used for the deter minative ratios in Crystal Data [1973].

In most cases, preliminary lattice constants were available in the literature, and were used for the initial indexing and refinement. In cases where such data were not available, other methods were tried. If suitable single crystals were available, the lattice constants were obtained by use of a four-circle diffractometer. Axial ratios and densities from Groth [1908] were sometimes useful. Cell constants were also found in some instances by use of the Visser computer program [1969].

A least squares program [Evans et al., 1963] assigned hk£'s and refined the lattice constants. In indexing cubic patterns, for a given reflection multiple hk£'s were not utilized in the refinement or reported. Instead, the single appropriate in dex having the largest h was used. Cell refine ment was based only upon 26 , values which could be indexed without ambiguity. The program mini mized the value I(6 obs-6 ., ) 2 . The estimated standard deviations (e.s.3. s) of the reciprocal cell parameters were determined from the inverse matrix of the normal equations. The program cal culated the e.s.d.'s of the direct cell constants by the method of propagation of errors. Since 1973, the e.s.d.'s derived by the computer program have been increased by 50% in order to reflect more truly the uncertainty in the lattice con stants. A similar increase should also be applied to all lattice constants published in this series prior to 1973. The e.s.d.'s in the least signif icant figures are given in parentheses following the lattice constants.

For each d-value, the number of significant figures was derived from the average error in |26 - 26 | and the equation Ad/d = -(cot6)A6. Witfi these conditions, the rounded value of d agrees with its appropriate 26 within the average error in 26. The value of A6 varies with the sum- metry and crystallinity of each sample.

Densities. These were calculated from the specified lattice constants, the Avogadro number 6.0220943 x 1023 [Deslattes et al., 1974] and 1977 atomic weights published by the International Union of Pure and Applied Chemistry [1979].

Figure of merit. Several figures of merit ratings are available for assessing indexed powder data. M20 [de Wolff, 1968] is a criterion for the reliability of the unit cell and indexing. A value of M20 > 10 will guarantee the essential correctness of the indexing provided there are not more than 2 spurious lines 0£20 < 2) [de Wolff, 1968]. In general, patterns reported in this publication had M20 > 20 and X = 0. M2 o is reported if a cell was derived only through com puter indexing from powder data, without further confirmation.

The accuracy and completeness of measured in- terplanar spacings is conveniently reported as F^ [Smith and Snyder, 1979]. The format joshed in this publication is FN = overall value (|A20|, N ), where N, the number of observed reflections ^wli chosen as 30, or the maximum number of lines of

Page 9: NBS25-18

the pattern if the entire pattern had fewer than 30 lines. The "overall value" is the figure of rneritj_F.,, as defined by Smith and Snyder [1979], and (A26| is the average absolute magnitude of discrepancy between observed and calculated 20 values for each reported hkA. N posg is the number of diffraction lines allowed in the space group, up to the Nth observed and indexed line. Co- positional lines such as the cubic 221 and 300 are counted as one possible line.

Intensity measurements. The intensities of the diffraction lines were measured as peak heights above background and were expressed in percentage of the strongest line. It has been found that samples which give satisfactory intensity patterns usually have an average particle size smaller than 10 pm, as recommended by Alexander et al. [1948]. In order to avoid the orientation effects which occur when powdered samples are packed or pressed, a sample holder was made that had in its top face a rectangular cavity which extended to one end of the holder. To prepare the sample, a glass slide was clamped over the top face to form a temporary cavity wall (see Figure 1), and the powdered sam ple was allowed to drift into the end opening while the holder was held in a vertical position. With the sample holder returned to a horizontal position, the glass slide was carefully removed so that the sample could be exposed to the x-ray beam (see Figure 2). As a general practice, ap proximately 50 volume percent of finely ground silica-gel was added as a diluent. Occasionally, a rotating sample holder was used.

As a check on reproducibility, each sample was mounted at least 3 times. The intensity values were determined for each of the mountings. The reported I re^value for each observed spacing is the average of 3 or more observations and is rounded to the nearest integer. Theta-compensating (variable divergence) slits were sometimes used to gather the intensity data. In that case, the average I(comp) for each spacing was converted to an equivalent fixed slit value, using the approxi mate equation:

I(fixed) = sin 6

The estimated standard deviation, a, in the relative intensity values was calculated from the values of the,five strongest lines, excluding the line with I =100.

and

a=m

where

m is the number of strong lines(usually 5), and

n is the number of independentobservations i, per line.

Figure 1.

Figure 2.

Where conversion of intensities for effects of theta-compensating slits was required, each a. was multiplied by the conversion factor

f - I(comp) I(fixed)

Reference intensity ratio, I/I corundum

The reference intensity ratio, I/I , has been de fined as the direct ratio of the intensity of the strongest reflection of a sample, to the inten sity of the 113 (hexagonal) reflection of corundum (a-Al 203 ) [Visser and de Wolff, 1964]. In this publication the ratios I/I are tabulated for cop per K(XI radiation, for a 1:1 mixture by weight ofthe sample and corundum, for very common phases.

I/I was determined only

A procedure has been adopted, to achieve greater statistical accuracy [Hubbard and Smith, 1977]. For any weight fractions of sample andcorundum, X and X (X = 1-X ), the intensities ' s c s c '

Page 10: NBS25-18

for reflection h of the sample and k of corundum were measured for several combinations of h and k usually within the same region of 26, to pro vide indications of possible preferred orienta tion, extinction, or other systematic errors. The reference intensity ratio is then given by

xe i rel (h) i c (k)

where (h ) indicates specifically which reflec tion was chosen for tabulation purposes. For each of our patterns, the reflection (h ) will be the one with I = 100 since only copper radiation was used. Typically, at least 3 sets of reflections and 2 mountings of the mixture were used to obtain 6 or more values for the reference intensity ratio, I/I . These values yielded, the tabulated aver- ageC<I/I >. From these data, the standard devia tion, a, was obtained from

T2 =n(n-l)

where n was the number of measurements of the reference intensity ratio. The standard deviation in the least significant figures is given in paren theses.

Format of tables. The printing of the data has been computerized. Superimposed reflections are treated in one of two ways. If a d-spacing has only two possible indices, an M is added to the d-spacing which is repeated on the next line, but with the second index. However, if there are more than two possible indices, a plus sign is used in like manner. In both cases, the composite intensity is printed only once and aligned with the first reflection. The symbol "1L" in the in tensity column is used to indicate "less than 1".

UNITSo o

In this publication the Angstrom unit (1A = 100 pm) was selected for presentation of the d- spacings and lattice parameters . This maintained consistency with (a) the earlier publications of Standard X-ray Diffraction Powder Patterns (Cir cular 539 and Monograph 25), (b) the publications of the International Union of Crystallography, and (c) the continuing publication of cards and search manuals of the PDF (now consisting of over 35,000 entries). The PDF search manuals are based on the d-spacings in A of the 3 strongest lines. Consis tent with the choice of the X unit for length, the volume of the unit cell is expressed in &3 (1A3 = 1 x 10~30 m3 ) . Densities are reported in g/cm3 (1 gm/cm3 = 10 3 kg/m3 ).

Beryllium Nitride, Be3N2

CAS registry no. 1304-54-7

SampleThe sample was obtained from Brush Beryllium Co., Cleveland, OH. The lattice constant reported here was obtained from a thin sample on a slide smeared with high vacuum grease. The peak positions from a thick sample are shifted to lower angles result ing from the penetration of the beam owing to the unusually low absorption of the sample. For a thick sample an apparent lattice parameter of 8.150 Jt would be expected for lines below 100 20.

ColorLight gray

StructureCubic, Ia3 (206), Z = 16. The structure was determined by von Stackelberg and Paulus (1933).

Calcium Sulfate Hydrate (Bassanite), CaS04 -0.5H20

SynonymPlaster of Paris

GAS registry no. 10034-76-1

SampleThe sample was prepared at NBS by adding H2S04 to an aqueous solution of Ca(N03 ) 2 to form CaS04 »2H20. The wet fresh material was mixed with concentrated HN03 , heated at 80 C, and held there for several days. Extremely fine crystals developed and were bottled while still moist. Just before measurements were taken, the crystals were dried in air at room temperature. The material was somewhat unstable, slowly changing to CaS04 -2H20 under conditions of high atmospheric humidity.

Consistent intensity data were difficult to obtain. The data here were measured on samples which had been side-drifted into holders, with no further packing or smooth ing. Other measurements on packed samples showed different intensities; in par ticular, the reflection at d=2.807 showed values as low as 19, and at d=1.847, the packed samples had values as low as 29.

ColorColorless

StructurePseudo-orthorhombic, I***, Z = 12. The literature on CaS04 -0.5H20 is extensive and confusing as noted by Gay [1965] and Clifton [1972]. The cell below was modified from one given by Gay [1965] who stated that the true symmetry was monoclinic, with p = 90 . This NBS cell was also consistent with one found by use of the Visser program and associated refinement procedures. Bushuev [1980] reported a similar monoclinic cell for CaS04 -0.67H20 with a=12.028, b=38.022, c=6.927, Y=90.21 , space group 12. There was no evidence to require the monoclinic cell for NBS data.

Lattice constants of this sample

a = 12.031(4) Ab = 12.695(6)c = 6.934(2)

a/b = 0.9477 c/b = 0.5462

Volume 0 1059.1 A3

Density(calculated) 2.731 g/cm3

PolymorphismTwo forms, Of and p have been described by several authors, as noted by Clifton [1972], He concluded that although slight differences have been observed between the properties of the two forms, it could not be conclusively determined whether the differences were sufficiently significant to consider the supposed a and p forms as separate entities.

IntensitiesThe crystals were long needles which oriented strongly, and the quantity was limited. Two sets of intensities are presented here. The first set was measured from only one experi mental pattern and may be distorted by orien tation. The 2nd set of I's was calculated from the structure data of Himes et al. [1981]. At 20 = 24.37, a calculated peak of intensity 3 was not observed on the experimental pattern.

CAS registry no. 12014-72-1

SampleThe sample was prepared at NBS by heating Ce02 and Nb20 5 at 1000 C for 21 hours, at 1500 C for 21 hours, and at 800 C for 4 days under a high vacuum.

ColorMedium bright green

StructureMonoclinic, I2/a (15), Z = 4. The structure of CeNb04 has been determined using neutron powder diffraction by Santoro et al. [1980]. This phase had earlier been reported to be in space group Ia(5) by Komkov [1959]. CeNb04 is isostructural with other rare earth niobates and tantalates [Roth et al., 1977]. The structure is a distorted scheelite type called beta-fergusonite-(Ce) or brocenite [Kuo et al., 1975],

Cobalt Phosphide, Co2 P

GAS registry no. 12134-02-0

SampleThe sample was obtained from ICN-K&K Labora tories, Plainview, NY. It contained a few percent of Co 3 (P04 ) 2 which did not interfere with measurements.

Color Black

StructureOrthorhombic, Pnam (62), Z = 4, isostructural with CogSi. The structure was determined by Nowotny [1947]. It was refined by Rundqvist [1960] who stated that there is an extended homogeneity range at elevated temperatures; the widening of the range is apparently connected with random vacancies in the metal atom sites.

Magnesium Phosphate, a-

SynonymMagnesium pyrophosphate

SampleThe sample was prepared at NBS. The com position of a commercially available sample of magnesium phosphate (mixed phases) was adjusted with additions of (NH4 )H2P04 . The mixture was fused and resolidified to yield single phase a-Mg2P20?- After being ground, the sample was annealed at 140 C for 5 hours and slowly cooled to room temperature.

ColorColorless

StructureMonoclinic, P2 x /n (14), Z = 4. The structure was determined by Calvo [1967].

Lattice constants of this sample

a = 8.9124(16) Ab = 8.290(2)c = 6.9492(15)p = 111.70(1)

a/b * 1.0751 c/b = 0.8383

Volume 0 477.05 A3

Density(calculated) 3.099 g/cm3

PolymorphismA high-temperature p-form exists and is also monoclinic, with a and c roughly half as large as in the a-phase. The phase trans formation was found to be reversible, and both phases coexist from 59 to 63 C [Calvo et al., 1967].

Neodymium Tantalum Oxide, NdTa04

SynonymNeodymium tantalate

GAS registry no. 12344-26-4

SampleThe sample was prepared at NBS by heating Nd203 and Ta205 overnight at 1000 C, grinding and reheating at 1600 C for a period of 16-20 hours, and quenched.

ColorVery pale violet

StructureMonoclinic, I2/a (15), Z = 4. The structure of NdTa04 has been determined using neutron powder diffraction by Santoro et al. [1980]. This phase was earlier reported to be in space group Ia(5) by Komkov [1959]. NdTa04 is isostructural with other rare earth niobates and tantalates [Roth et al., 1977]. The structure type is a distorted scheelite called beta-fergusonite (Ce) or brocenite. [Kuo et al., 1975].

Lattice constants of this sample

a = 5.5136(7)Ab = 11.2356(8)c = 5.1151(5)P = 95.717(11)

a/b = 0.4907 c/a = 0.4553

Volume 0 315.30 A3

Density(calculated) 8.199 g/cm3

PolymorphismWhen heated to about 1320 C NdTa04 undergoes a readily reversible phase change to a tetragonal structure of the fergusonite type, very similar to scheelite, CaW04 [Stubican, 1964].

SampleThe sample was prepared at NBS using BaTi03 , Ti02 , and very low alkaline content Nd203 . Stoichiometric amounts of the constituents were blended with mortar and pestle, then calcined in a platinum crucible, with periodic grindings. An initial calcine at 1250 C for 1 day, followed by a second heating at 1350 C for about 3 days was sufficient to yield a single phase product.

PolymorphismNaNb03 becomes tetragonal at about 225 C, and cubic near 435 C [Wood, 1951]. Wood et al. [1962] described a field-induced ferroelectric polymorph which has a cell similar to the orthorhombic phase except that the £ is halved. Bulakh et al. [1962] described a new mineral, natroniobite, which is principally NaNb03 and presumably monoclinic.

bibliography or literature survey, mention it here)

Standard x-ray powder diffraction patterns are presented for 58 substances. These experimental patterns, useful for identification, were obtained by diffractometer methods. The lattice constants were refined by least-squares methods, and reflections were assigned Miller indices consistent with space group extinctions. Relative intensities, calculated densities, literature references, and other relevant data are included.

12. KEY WORDS (Six to twelve entries; alphabetical order; capitalize only proper names; and separate key words by semicolons)

Crystal structure; densities; lattice constants; powder patterns; reference intensities; standard; x-ray diffraction.
