Silicon carbide refractory bricks are refractory materials made from silicon carbide (SiC). They exhibit good wear and corrosion resistance, high strength at high temperatures, high thermal conductivity, low linear expansion coefficient, and excellent thermal shock resistance.

Silicon carbide refractory bricks can be classified based on the content of SiC and the type of bonding phase. The performance of the refractory bricks largely depends on the condition of the bonding phase. Refractory bricks with bonding phase of silicon carbide can be categorized into: oxide bonded—using alumino-silicate or silicon dioxide as the bonding phase; nitride bonded—using silicon nitride (Si3N4), silicononitride (Si2ON2), or zirconia as the bonding phase; recrystallized—directly bonded through the recrystallization method between silicon carbide particles; and semi-carbide refractory bricks, which can further be divided into various types, such as clinker silicon carbide refractory bricks + high-alumina silicon carbide refractory bricks, zirconia-silicon carbide refractory bricks, silicon carbide-graphite refractory bricks, mullite-silicon carbide refractory bricks, and corundum-silicon carbide refractory bricks, etc.

The silicon carbide bricks produced by Gongyi Hongfeng Refractory Material Co., Ltd. are made from 98Sic raw material, bonded with oxides, and undergo high molding and high-temperature firing. They feature high high-temperature strength, excellent wear resistance, good corrosion resistance, high thermal conductivity, low thermal expansion coefficient, good thermal shock stability, and strong thermal radiation.
