Silicon carbide material have the advantages of wear resistance, corrosion resistance, high hardness, low density and high high temperature strength, so in recent years, Silicon carbide material has been rapidly popularized in various fields and has developed very rapidly. In the aerospace, nuclear industry, petroleum industry, chemical industry, textile industry, food industry and other need in high temperature, high speed, corrosion resistance, vacuum, electrical insulation, non-magnetic, dry friction and other special environment, this new type of ceramic material unparalleled alternative role is being gradually recognized.

The high temperature bending strength of silicon nitride bonded silicon carbide plate is 4 to 8 times that of ordinary refractory materials. The coefficient of thermal expansion is half of that of high aluminum refractory; The thermal conductivity is 7 to 8 times that of general refractories, and the strength increases with the increase of temperature. When the temperature rises to 1400℃, the strength begins to decline; However, the bending strength index is still maintained at normal temperature when the temperature drops to 1500℃, and the thermal conductivity of the material gradually decreases with the increase of temperature. It has the characteristics of high density, high strength, good thermal shock stability, high softening point under load, good thermal conductivity, high resistance value, and excellent melting erosion resistance and oxidation resistance of cryolite, aluminum fluoride, sodium fluoride and calcium fluoride. Its performance is described as follows:

The characteristics of Nitride bonded silicon carbide batts, it not only has high density, high strength, good thermal shock stability, high softening point under load, good thermal conductivity, high resistance, but also has excellent resistance to cryolite, aluminum fluoride, sodium fluoride and calcium fluoride melting erosion and oxidation resistance. Mainly used in building sanitary ceramics, daily porcelain, electric porcelain, aluminum, copper, zinc, steel and steel rolling, iron, metal heat treatment, environmental protection and other fields.
