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.

碳化铬改性反应烧结碳化硅的结构化

研究了碳化铬改性反应烧结碳化硅 (RSSC) 的结构和相组成。当使用六方碳化硅时，碳化铬对 RSSC 的改性稳定了二次碳化硅的立方晶格。当样品用液态硅浸渍时，会形成硅在碳化铬中的固溶体。在多孔样品的浸渍中，硅影响碳化铬颗粒的固结，因为它们被液态硅取代。根据起始碳化硅的粒度和特征，RSSC 具有各种结构修改的特点。六边形 6H 结构出现在由碳在碳化硅中的纳米立方固溶体产生的 RSSC 中。
