Silicon nitride bonded silicon carbide brick is produced by reaction sintering method. It is fired at high temperature in nitrogen atmosphere. Silicon nitride and silicon carbide form a network structure and are combined together. Therefore, the product has the following remarkable characteristics.
1. High purity, no SiC and Si3N4 as the main components, and few magazines
2. Good thermal shock resistance
3. Good oxidation resistance
4. Strong wear resistance
5. Good slag corrosion resistance, good corrosion resistance to cryolite, aluminum fluoride, etc
6. Good thermal conductivity and energy saving effect
