Moissanite - Wikipedia

Moissanite (/ˈmɔɪsənaɪt/)[4] is naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide is useful for commercial and industrial appliions due to its hardness, optical properties and thermal

Silicon Carbide (SiC) Micron and Nano Powder - …

Silicon carbide, chemical formula SiC, is a covalent bond material. C and Si belong to the same family, all have a tetravalent bond, while Si also has metal properties. Its structure has the mesh shape and body shape and has high strength in nature, so the properties of silicon carbide material include high-temperature strength, wear-resistant, corrosion-resistant, high thermal conductivity
