Silicon nitride bonded silicon carbide brick
Introduction:
Silicon nitride bonded silicon carbide is a refractory product sintered by nitriding using SiC and Si powder as raw materials. The silicon nitride formed by the reaction of Si and N2 forms a very strong bond, and the SiC particles are combined.
Advantages:
Good alkali corrosion resistance, oxidation resistance, wear resistance, high thermal conductivity, thermal shock resistance, extremely low conductivity, energy saving, long life and no pollution
Application:
Lining of blast furnace, lining of aluminum reduction electrolytic cell, ceramic kiln furniture, blast furnace outlet water cooling pipe set brick
