The manufacturing process of silicon carbide products for process equipment applications includes three main steps. First the silicon carbide parts are shaped by extrusion (tubes) or cold isostatic pressing (plates and blocks). Then they are machined (plates and blocks). Finally, they are sintered under vacuum at a very high temperature. This demanding process confers its properties to the material.
Silicon carbide has outstanding properties. It shows outstanding thermal conductivity as well as extremely high compression, tensile and flexural strengths.
Pressureless sintered silicon carbide is almost universally corrosion resistant. It resists to all common acids (e.g. hydrochloric acid, sulfuric acid, hydrobromic acid, and hydrofluoric acid), to bases (e.g. amines, potash and caustic soda), to all solvents, and to oxidizing media (e.g. nitric acid).
