Abstract
A study is made of the effect of particle dimensions of the initial carbon and silicon carbide powders on the structure of compacts in the SiC ― carbon system. It is established that carbon can be distributed among the SiC grains by three different schemes: interstitial, substitutional, and displacement. The factors which determine the carbon distribution scheme are the relative concentrations of the components in the semifinished products and the dimensions of the particles of the initial powders. Specimens in which carbon is distributed in accordance with the interstitial scheme have the best characteristics.
