Abstract

Base positions of crystallography of polytypic carbide of silicon are considered. Influence of different technological factors is shown such as: temperature, maintenance of admixtures and terms of forming of crystals on polytypic composition of material. X-ray structure studies of industrial and experience carbide of silicon are undertaken. The fundamental differences of polytypic composition of the investigated materials are shown.
