Silicon carbide bricks
Silicon Carbide Bricks, Silicon Nitride Bonded Sic Brick / SiC bricks are made of high quality synthetically made silicon carbide grains (SiC) and selected bonding components, including nitride, Si3N4.
Silicon Carbide Bricks have great features such as low thermal expansion coefficient, high thermal conductivity, high thermal shock resistance, high corrosion resistance, high bending strength, and excellent resistance to liquid aluminum erosion capability.
SiC brick is particularly ideal for application in high temperature furnaces and in waste incineration plants.
Silicon Carbide Brick, also known as Silicon Carbide Fire Brick
The SiC blocks are widely used as lining bricks of large aluminum electrolytic cell. Using nitride bonded silicon carbide products enlarges the tank capacity, improves the thermal conductivity, enables rapid cooling, and increases the tank production capacity at the same time. Alumina and cryolite of eutectic content can form on brick’s surface, which can protect the tank lining work layer, and prolong the tank’s service life. Therefore, silicon nitride bonded silicon carbide bricks are widely used in the aluminum industry.
SiC products are based on synthetically manufactured silicon carbide grains with selected bonding components and metal oxide additives tuned to the use. The excellent characteristics of SiC products, such as high thermal conductivity and high corrosion resistance against numerous process media make it particularly ideal for use in high temperature furnaces and in waste incineration plants.
Silicon carbide is produced synthetically and possess properties such as oxidation resistance, low density, high strength, high temperature strength, high thermal shock resistance, low thermal expansion, and good chemical resistance. Replacement of pure silicon semiconductors with silicon carbide technology, semiconductors is anticipated to have a positive impact on the market over the next five years. Silicon carbide is segmented into types such as black, green, coated, refractory, metallurgical briquettes, metallurgical, and micro grit. Silicon carbide finds application in abrasive cloths and paper products and in grinding wheels owing to its superior properties such as high thermal resistance, hardness, and high temperature strength. Substituting pure silicon with silicon carbide in semiconductors is a key factor expected to drive the demand for silicon carbide in semiconductor and electronics industry.
