SiC
ceramicSilicon carbide (SiC) is a hard ceramic compound formed from silicon and carbon, known for exceptional hardness, thermal stability, and chemical resistance across a wide temperature range. It is widely used in demanding high-temperature and high-stress applications including semiconductor devices, refractory linings in furnaces and kilns, abrasive grinding media, and structural components in aerospace and automotive engines where thermal shock resistance and lightweight strength are critical. SiC is preferred over alumina and other traditional ceramics in applications requiring superior thermal conductivity combined with mechanical strength, making it essential in next-generation power electronics, electric vehicle components, and extreme-environment engineering.
