Description

What is the Sic Refractory Brick

Silicon carbide bricks are burned firebricks which adopts industrial SiC as main raw material. The binders used to make SiC brick include: aluminum silicate, nitride, etc. SiC based firebricks, which contain less than 50% of SiC, is called semi SiC bricks. Semi SiC refractory bricks include clinker SiC bricks, high alumina SiC bricks, zircon SiC bricks, mullite SiC bricks, corundum SiC bricks, etc. Silicon carbide bricks character in high cold and hot mechanical strength, low linear expansion rate, high thermal conductivity, good thermal shock resistance, excellent high temperature wear resistance and strong chemical corrosion resistance.

Silicon Carbide Bricks Application

silicon carbide bricks are steel industry, nonferrous metals industry, chemical industry, power plants, ceramics industry and so on.
