Abstract
An experimental determination on powder mixtures of SiC-3C and 6H polytypes using an X-ray goniometer system showed the possibility of quantitative determination of polytype fraction directly from peak intensities. In combination with calculated X-ray intensities of 15R and 4H polytype, the method yields a simple equation system for the relative quantities of SiC polytypes 15R, 6H, 4H and 3C in polycrystalline samples and powder mixtures.
