Silicon Carbide

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).

Manufacturing process

Silicon carbide for process equipment applications is manufactured by the sintering process. 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 ultimate corrosion resistance, its extreme hardness, and its mechanical properties to our CORROSIC® material. 

Properties and corrosion resistance

Properties

With thermal conductivity of 130 W/m.K, silicon carbide outperforms most of the materials used for the construction of corrosion-resistant process equipment.
