Product Description
(SSIC) Silicon Carbide Mechanical Seal Reaction Bonded (SSIC)
Nowadays, customers are used to apply silicon carbide as the non-oxidation ceramic material; the silicon carbide owns better hardness, heat-resisting, anti-oxidation, anti-corrosion and high thermo conductivity than ordinary ceramic materials. Recently, the silicon carbide 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 silicon carbide (S-SiC):
The sintered silicon carbide (S-SiC) products are our major products supplying to market.
The sintered silicon carbide (S-SiC) material has a mechanical performance similar to the HP-silicon carbide (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 S-SiC completely meets the requirements of producing mechanical seals and parts of spindle-seal-free pumps (shielded pumps) or magnetic pumps; sintered silicon carbide (S-SiC) now is the silicon carbide ceramic material so popular in overseas industries.
The sintered silicon carbide organization is formed by α-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 sintered silicon carbide (S-SiC) and graphite is the seal pair with the highest PV value in application. The high-purity sintered silicon carbide (>98% silicon carbide) 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.
