■ Introduction:
Refractory NSIC nitride boned silicon carbide crucible sagger for melting is usually used for high temperature applications, such as the melting and casting of metals, alloys and other materials. The refractory silicon carbide crucible are made of a combination of silicon carbide and silicon nitride and have excellent impact resistance, high thermal conductivity, and chemical resistance.
