Silicon Carbide for functional ceramic making
Description
Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted by electric furnace at high temperature. It can used for refractory purpose or in electronic industry.Silicon Carbide also has the resistivity necessary to perform as a semiconductor material. Because of these properties, Silicon Carbide is used in a wide range of applications and industries.
Characteristic of silicon carbide
- High hardness
- Good thermal conductivity
- Thermal expansion coefficient is small
- Wear resistance
Application of silicon carbide
- Ceramic making
