S-SiC
Properties & Application Areas
Silicon Carbide is the Outstanding Choice of High-Performance Materials
Silicon carbide possesses remarkable performance characteristics. It has an extremely high hardness and strong wear resistance. Its thermal conductivity is high, endowing it with excellent heat dissipation performance. Moreover, it exhibits good chemical stability and is resistant to corrosion.
S-SiC
Sintered Silicon Carbide
Usually, the pressureless sintering process is adopted. High-purity silicon carbide powder is mixed with a small amount of additives, and then heated to around 1800°C to 2000°C in a high-temperature furnace for sintering. A dense ceramic structure is formed through the diffusion and fusion of particles.
