STANDARD X-RAY DIFFRACTION POWDER PATTERNS Section 10 - Data for 84 substances Howard E. Swanson, Howard F. McMurdie,' Marlene C. Morris/ Eioise H. Evans,^ and Boris Paretzkin^ Assisted by Johan H. deGroot^ and Simon J. Carmel Standaid x-ray diffraction patterns are presented for 84 substances. Forty-seven of ttiese patterns represent experimental data and 37 are calculated. The experimental x-ray powder diffraction patterns were obtained with an x-ray diffradometer. All d-values were assigned Miller indices determined by comparison with computed inlerplanar spacings consistent with space group extinctions. The densities and lattice constants were calculated, and the refractive indices were measured whenever possible. The calculated x-ray powder diffraction patterns were computed from published crystal structure data. Both peak height and integrated intensities are re- ported for the calculated patterns. Key words: Crystal structure; integrated intensities; lattice constants; peak intensities; powder patterns; reference intensities; standard; x-ray diffraction. INTRODUCTION Optical data, color. A microscopic inspection for phase purity was also made on the non-opaque materials during The Powder Diffraction File is a continuing compilation of the refractive index determination. The latter was done by diffraction patterns gathered from many sources.
