Silicon Carbide (SiC)
Silicon Carbide has the highest chemical resistance and hardness of all Fine Ceramics. Especially, solid-phase sintered silicon carbide is an excellent heatresistant material that does not deteriorate in strength even at 1400°C. Furthermore, it is used in a wide range of industries, including mechanical seals and pump parts due to its excellent sliding properties, and semiconductor processing equipment and general industrial machine parts due to its high thermal conductivity and electrical semi-conductivity.
- Important property :
- Chemical Resistance
- High Strength
- Semiconductive
