5N SiC powder Cubic beta silicon carbide 100nm 300nm 500nm

5N SiC powder Cubic beta silicon carbide 100nm 300nm 500nm

High-purity beta silicon carbide is β-phase silicon carbide with a purity of 5N or higher. β-phase cubic silicon carbide has a 3C cubic crystal structure, and its unique crystal morphology gives it a hardness approaching that of diamond, with a Mohs hardness of 9.5-9.75. High-purity β-silicon carbide powder is produced using high-temperature thermosetting and chemical vapor deposition (CVD) methods. The product features high purity, high beta phase content, controllable particle size, excellent sintering activity, and good dispersibility. Simultaneously, cubic silicon carbide possesses excellent physicochemical properties, such as high thermal conductivity, high electron drift velocity, high electron mobility, corrosion resistance, and good thermal shock resistance. It is widely used in aerospace, high-end ceramics, new energy batteries, surface treatment, and semiconductor industries.
