Black Silicon Carbide Introduction
Because of the rarity of natural moissanite, most silicon carbide is synthetic. It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 °C (2,730 °F).
Feature of SIC powder:
High Purity, Superior Quality: Our silicon carbide sic powder stands out for its remarkable purity and high silicon content. This characteristic purity ensures optimal performance and longevity in refractory settings, meeting stringent industry standards.
Enhanced Thermal Stability: Experience the benefits of a material with small thermal expansion, showcasing superior resistance to thermal stress. This feature enables sustained performance even in environments with varying temperatures, ensuring durability and reliability.
Unmatched Corrosion Resistance: Built to endure, our silicon carbide powder boasts exceptional corrosion resistance. Its robust structure shields against chemical attacks, making it an ideal choice for harsh industrial environments.
