Application of silicon carbide in refractory materials
High thermal conductivity
Since silicon carbide itself has good thermal conductivity, refractory materials with high silicon carbide content have high thermal conductivity, and most of their thermal conductivity exceeds 14.4W/(m·K). Used in heat exchangers, saggers, water-cooled walls of coal gasification furnaces, indirectly heated kiln furniture products, etc. During the use of silicon carbide products, the thermal conductivity of the particle surface will gradually become smaller. The properties of the bonding base material have a certain impact on the thermal conductivity of silicon carbide products. The thermal conductivity of silicon oxynitride bonding and silicon nitride bonded silicon carbide is higher, while the thermal conductivity of silicate bonded silicon carbide is smaller.
