Product introduction of silicon carbide castable
Silicon carbide castables are made of high-grade silicon carbide and industrial silicon powder. The silicon carbide content of refractory silicon carbide castables is generally between 80 and 95. It is made of refractory aggregate, refractory powder, adhesive and other additives.
Features of silicon carbide castable
- High temperature strength
- High thermal conductivity
- Low linear expansion coefficient
- Good thermal shock resistance
- Good wear resistance and corrosion resistance
