Nowadays, customers are used to apply silicon carbide(SiC)as the non-oxidation ceramic material; the SiC owns better hardness, heat-resisting, anti-oxidation, anti-corrosion and high thermo conductivity than ordinary ceramic materials. Recently, the SiC material is widely applied in mechanical structures and chemical seal parts; it is applied in extreme harsh working environments such as under strong acid, alkali, heavy wear, high temperature or aviation & space traveling conditions.
Sintered SiC (S-SiC):
The sintered silicon carbide(S-SiC) products are our major products supplying to market.
The sintered silicon carbide material has a mechanical performance similar to the HP-SiC material; yet, its workmanship is superior to HP-SiC and cheaper in production cost, suitable to mass production or products with complicate shapes. The sintered silicon carbide completely meets the requirements of producing mechanical seals and parts of spindle-seal-free pumps (shielded pumps) or magnetic pumps; sintered silicon carbide now is the SiC ceramic material so popular in overseas industries.
The sintered silicon carbide organization is formed by £\-SiC crystals; the volumetric density can reach over 98% (3.1g/cm3) of its theoretic one. Its density is 1/5 of tungsten carbide, and hardness is only second to diamond, performing extremely excellent efficiency in anti-grain-wear practice. So far, the combination of S-SiC and graphite is the seal pair with the highest PV value in application. The high-purity sintered silicon carbide (>98% )SiC can withstand chemical corrosion of various kinds under high temperature condition. The sintered silicon carbide bears extremely high specific strength; and its anti-oxidation capability and mechanical properties under high-temperature status are excellent as well.
