Product Description

Silicon carbide brick, also known as SiC brick, is a refractory material made of silicon carbide as the main raw material, mixed with various binding agents and fired at high temperature. Silicon carbide has excellent properties such as high strength, high temperature resistance, wear resistance, corrosion resistance, and thermal shock resistance, which makes SiC brick an ideal material for use in high-temperature industrial applications.

SiC bricks are classified into different grades based on their silicon carbide content, such as 70%, 80%, and 90%. The higher the SiC content, the higher the temperature resistance and the better the performance of the SiC brick. SiC bricks can also be classified into different types based on their shapes, such as standard shapes, special shapes, and customized shapes, to meet the different needs of various industrial applications.
