Silicon Carbide Bricks Compositions
The raw materials of the silicon carbide bricks are silicon carbide, about 72%-99%. Silicon carbide is also called the moissanite, corundum sand or refractory sand. It is made by quartz sand, petroleum coke or coal tar, and wood bits, being produced by high temperature smelting in the electric resistance furnace.
Silicon Carbide Bricks Properties
Silicon carbide block belongs to neutral refractory, which withstands erosion of acid and alkali slags, solvents, and other chemical corrosion. Silicon carbide has characters of high strength, good anti-oxidation resistance, and no transformation at high temperature. In all raw materials of the non-oxide refractory bricks, silicon carbide brick is the most economical and most widely used one. It can be used in different industries, such as the stone industry, glass industry, metal industry, printing industry, and light industry. Besides, it can be made into turbine blades of the high temperature gas turbine, or used as anti-wear sealing materials, etc.
With the characters of the silicon carbon, silicon carbide brick is featured with high refractoriness, high strength, good thermal conductivity, good impact resistance, good wear resistance, thermal shock resistance, and erosion resistance.
