Rongsheng Silicon Carbide Bricks for Sale. Silicon carbide refractory materials. Silicon carbide (SiC) products refer to a kind of advanced refractory materials with SiC as the main component, which are made by firing industrial SiC as raw materials. Silicon carbide bricks have a series of excellent properties such as high strength at room temperature and high temperature, high thermal conductivity, small linear expansion coefficient, good thermal shock resistance, excellent high-temperature wear resistance, and strong resistance to chemical corrosion. Silicon carbide bricks are widely used in industrial fields such as steel, non-ferrous metallurgy, chemistry, electricity, ceramics, and aerospace.

Classification of Silicon Carbide Bricks

SiC products can be classified according to SiC content, binder type, and addition amount. The performance of silicon carbide bricks depends largely on the bonding condition between SiC particles in the material. Therefore, refractory manufacturers usually classify SiC products according to the type of bonding phase. According to the different bonding phases, silicon carbide bricks can be divided into:

• (1) Oxide-bonded silicon carbide bricks. With Al2O3-SiO2 silicate as the bonding phase, including clay-bonded, mullite-bonded and SiO2-bonded SiC.
• (2) Nitride-bonded silicon carbide bricks. The bonding phase is covalently bonded compounds such as Si3N4, Si2N2O, Sialon, etc.
• (3) Self-bonded silicon carbide bricks. Including β-SiC bonded SiC and recrystallized SiC.
• (4) Silicon-infiltrated reaction-sintered silicon carbide bricks. A SiC-based engineering ceramic material composed of SiC and free Si.

In addition, silicon carbide brick products with a SiC content of less than 50% are usually called semi-SiC products. Semi-SiC products include clinker SiC products, high-aluminum SiC products, zircon SiC products, mullite SiC products, and corundum SiC products.

Uses of Silicon Carbide Bricks

SiC products are high-grade refractory materials. Rongsheng Silicon Carbide Bricks have high mechanical strength, high thermal conductivity, good thermal shock resistance, and wear resistance.
