Details Introduction
Silicon carbide bricks are refractory products made primarily from silicon carbide. The silicon carbide content ranges from 72% to 99%. Generally, black silicon carbide (with SiC content above 96%) is selected as the raw material, with or without the addition of a binder, and is produced through processes such as batching, mixing, forming, and firing. The main crystal phase is silicon carbide. The main varieties include oxide-bonded silicon carbide bricks, carbon-bonded silicon carbide bricks, nitride-bonded silicon carbide bricks, self-bonded silicon carbide bricks, recrystallized silicon carbide bricks, and semi-silicon carbide bricks. They have characteristics such as wear resistance, good corrosion resistance, high-temperature strength, good thermal shock stability, high thermal conductivity, and low thermal expansion coefficient.
