1/8/2018· The porous RBSC ceramics exhibited excellent corrosion resistance in acid and basic solutions. The anti-oxidation temperature of the porous RBSC ceramics could reach 1200 °C in air. The RBSC ceramics maintained the bending strength of 17.5 MPa after 60 cold-hot cycles in air (0–800 °C).
Corrosion resistance. Pressureless sintered silicon carbide is almost universally corrosion-resistant. It resists against all common acids (e.g. hydrochloric acid, sulfuric acid, hydrobromic acid, and hydrofluoric acid), bases (e.g. amines, potash and caustic soda), all solvents, and oxidizing media (e.g. nitric acid).
Its high resistance to wear also makes Silicon Carbide an ideal material for manufacturing abrasive resistant pipe, impellers, pumping chaers and other high wear parts. Its wear resistance (abrasiveness) is 5-20 times than that of cast iron and rubber.
Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.

There are several ways to evaluate thermal resistance: you can analyze the thermal resistance between junction and case or the thermal resistance between junction and environment. The thermal resistance between junction and environment is a useful parameter when external heat sinks are not connected, for example in those cases where you want to compare the thermal performance of different packages.
