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). The graph below shows the
Silicon carbide is mostly used in appliions that require high thermal conductivity. Its extreme hardness, resulting extraordinary resistance to wear, and excellent chemical resistance are the distinguishing qualities of this material. It has become an irreplaceable cornerstone of chemical process engineering, milling processes and dispersion technology.

11/3/2019· The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.

Silicon nitride, like aluminium oxide, is very hard and very chemically resistant. In terms of impact strength, silicon nitride comes close to zirconium oxide and is therefore used in all areas of mechanical and plant engineering. However, the biggest advantage of silicon nitride lies in its high resistance to temperatures and temperature changes.
It has high strength at elevated temperatures. For example, at 1000oC, SiC is 7.5 times stronger than Al203 (aluminum oxide). Black SiC will contain some free silicon and carbon and thus is not as pure as green SiC. Black will range in purity from 97-99% pure
