Abstract
Detailed X-ray and electron microscopy analyses of Cs2SO4 powders consisting of sphere- and platelike crystallites have been carried out. It is established that the intensity distributions of X-ray reflections in both cases radically differ, with the position on the diffraction-angle axis retained in accordance with the PDF-2 database. Electron microscopy microdiffraction investigations of the orientation of developed surfaces of platelike crystallites revealed four different directions; however, these directions could not provide texture amplification of a number of observed (hkl) reflections. It is suggested that the intensity redistribution is based on the sphericity of X-ray waves incident on the sample.
