Nitride Bonded Silicon Carbide Refractories

The silicon nitride bonded silicon carbide refractories are mainly composed of silicon nitride and silicon carbide as the main raw materials, and is mixed with organic materials, mixed, extruded or cast, dried and nitride. Silicon nitride bonded silicon carbide is a new type of refractory material. Widely used, the temperature is 1400 °C, has good thermal stability, thermal shock performance is better than ordinary refractory and recrystallized Sic, anti-oxidation, acid and alkali resistance, wear resistance, and has high flexural strength. It is resistant to erosion, erosion, non-contamination, and fast heat conduction in molten metals such as aluminum (Al), lead (Pb), zinc (Zn), and copper (Cu)
