Silicon Nitride Bonded Silicon Carbide
1. High strength. 
2. Volume stability. 
3. Good thermal conductivity. 

Metal silicon is the main raw material. According to different requirements of manufacturers, we produce various shapes of the adobe. After drying, metal silicon, it is with high purity nitrogen reaction sintered in the nitrating furnace. The product has a high temperature, high strength, volume stability and good thermal conductivity, acid, alkali and a variety of molten metal erosion ability and so on. 
The material is widely used in colored aluminum tank, zinc vertical tank; metallurgical industry, blast furnace lining, ceramic kiln shelf panels, pillars, separated flame plate; waste incineration furnace lining and other industries. 
Products, dimensions, physical and chemical indicators of useful life are up to customers' requirements.
