Silica-bonded silicon carbide brick

Introduction:

The silica-bonded silicon carbide product is prepared by adding a certain amount of quartz powder to the furnish, and bonding the silicon carbide particles by contacting the silicon carbide film formed by the surface oxidation of the fired silicon carbide particles. It can be formed by semi-dry or plastic molding.

Advantages:

Good thermal shock resistance, wear resistance, high thermal conductivity, small thermal expansion coefficient.

Application:

Metallurgy, ceramics, building materials and other industries
