Silicon Carbide

Silicon Carbide is an often used non-oxide ceramic material. Because silicon carbide has better hardness, heat resistant, oxidation resistant, corrosion resistant and high thermal conductivity, it has been widely used engineering machine's components and chemical engineering's sealing parts. Even silicon carbide has been used on strong acid, strong alkali, high abrasion, high temperature and aerospace etc. environment.

Atmospheric sintering silicon carbide are made of α-SiC crystals. Volume density could reach up to 98% (3.1g/cm3). Its density is tungsten carbide's one fifth. Its hardness is second only to diamond, has superior abrasion resistance. S-SiC paired graphite is highest PV value seals for now. High purity atmospheric sintering silicon carbide (>98% SiC) can resist various acid-base corrosion reaction under high temperature. S-SiC's specific strength extremely high, also, its high temperature resistance, oxidation resistance and high temperature mechanic behaviour are superior too.
