Product Introduction

Silicon Carbide Brick is a kind of refractory product mainly made of SiC, and the silicon carbide content is 72%~99%. Generally, it’s made by the black silicon carbide( content above 96%).

Features

1.Good abrasion Resistant.
2.Good Strength at High Temperature.
3.Good Thermal Shock Resistance.
4.Small Thermal Expansion Rate.

Application

Silicon carbide bricks can be used for metallurgical steel cylinder lining, nozzle, plug, blast furnace bottom ,non-ferrous metal smelting still, electrolytic cell side wall, smelting metal crucible, silicate industry furnace sheds and flame-proof materials, oil and gas generators in the chemical industry, organic waste combustion furnaces and aluminum refining furnace linings, etc.
