Nitrogen silicon carbide brick

Nitrogen Silicon Carbide Brick is silicon carbide products which main combination with silicon nitride. Generally,nitrogen silica carbide brick contain silicon carbide with 70% to 75% and 18% of the silicon nitride to 25%.Nitrogen silica carbide brick is also with good corrosion resistance, 1400 ℃ bending strength of up to 50 ~ 55MPa, porosity of 15% and coefficient of thermal expansion(4.5～5.0)×10-2℃-1. Nitrogen silica carbide brick is used for the main blast furnace air, the aluminum reduction cell lining, and so on.
