Customized Production Of High Purity Silicon Carbide Bricks For Furnaces
Description of of Silicon Carbide Brick
Silicon carbide bricks are refractory products made of silicon carbide as the main raw material. Silicon carbide content is 72%~99%. Generally, black silicon carbide (with more than 96% SiC content) is used as raw material, with binder (or without binder) added, and is prepared through batching, mixing, molding, firing and other processes. The main crystalline phase is silicon carbide. The main varieties are 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.

Features of Silicon Carbide Brick

1.Good thermal conductivity
2.Good high temperature strength
3.Wear resistant and erosion resistant
4.Good thermal shock resistance
5.Good corrosion resistance
6.Good oxidation resistance.
Applications of Silicon Carbide Brick:
ilicon carbide bricks find applications in industries such as metallurgy, ceramics, glass, cement, and other high-temperature processes. They are used in areas of furnaces, kilns, and other high-temperature equipment.
