Silica Carbide Brick Composition Silicon carbide brick is a kind of high-tech silicon carbide refractory brick which is through by mixing high-purity silicon carbide coarse powder and high-activity silicon carbide fine powder, and after being formed by slurry casting, vacuum sintering at a high temperature of 2450 to make its recrystallization.
The silicon carbide ceramic contains silicon carbide crystals having 0.1 to 25 mass % of 4H—SiC silicon carbide crystals and 50 to 99.9 mass % of 6H—SiC silicon carbide crystals, preferably having a nitrogen content of 0.01 mass % or less, more preferably
Nitride-bonded silicon carbide ceramics have lower processing costs than many other SiC-based ceramics and adequate properties for use as high-temperature heat exchangers in oxidizing environments. Silicon nitride has much better resistance to attack by chlorine at temperatures above 900 C than silicon carbide.

Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.
Silicon Nitride Bonded Sic Brick, Silicon Carbide Brick, SiC … Silicon Carbide bricks has great features such as high thermal conductivity, high thermal shock resistance, low thermal expansion coefficient, high corrosion resistance, high bending strength, and excellent resistance to liquid aluminum erosion capability.
Sialon bonded silicon carbide bricks, characterized by good resistance to oxidation and alkali corrosion, are mainly used on the underside, belly and bosh of blast furnace. This product was awarded the third prize of the National Science and Technology Award in 1998.
Silicon carbide (SiC) is a synthetic, semiconducting fine ceramic that excels in a wide cross-section of industrial markets. Manufacturers benefit from an eclectic offering of silicon carbide grades due to the availability of both high-density and open porous structures.
Silicon carbide, also known as carborundum, is a ceramic product made up of silicon and carbon atoms bonded in a crystal lattice. It has the chemical formula SiC. It was first discovered by a young scientist named Dr. Edward Goodrich Acheson, who was trying to make synthetic diamonds.
