The x-ray powder diffraction pattern and lattice parameters of perovskite

Abstract

The interplanar spacings and intensities of all lines appearing in the X-ray powder diffraction pattern of perovskite have been calculated. Many of the lines occur in groups with a large amount of overlap. As an aid to identifying the lines which are observed the intensity profiles of the major groups have been plotted. Those lines which are relatively free of overlap and can be identified unambiguously have been used to calculate the lattice parameters with the results a=5.4424 +- 0.0001 A b=7.6417 +- 0.0002 A c=5.3807 +- 0.0001 A.
