The structurization and phase composition of reaction-sintered silicon carbide (RSSC) modified by chromium carbide are examined. When hexagonal silicon carbide is used, the modification of RSSC by chromium carbide stabilizes the cubic lattice of secondary silicon carbide. A solid solution of silicon in chromium carbide is formed when the samples are impregnated with liquid silicon. In the impregnation of porous samples, silicon influences the consolidation of chromium carbide particles because they are displaced by liquid silicon. Depending on the particle size and features of starting silicon carbide, RSSC is characterized by various structural modifications. A hexagonal 6H structure shows up in RSSC produced from the nanosized cubic solid solution of carbon in silicon carbide.
