Corrosion resistance

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).

The graph hereunder shows the corrosion rates of silicon carbide in mg/cm2.a with different chemicals. Considering the density of SiC, 9.9 mg/cm2.a is equivalent to 32.5 μm/a or 1.28 mpy. 0.2 mg/cm2.a is equivalent to 0.65 μm/a or 0.02 mpy.
