With high overall density and very few internal pores, it is suitable for various high-temperature melting, sintering, experimental melting and other working conditions. It has high-temperature resistance, resistance to metal melt erosion, thermal conductivity and electrical conductivity, and thermal shock resistance. And it has a dense structure without leakage, high mechanical strength, which can be used for long-term repeated cycles. So it can meet the static load requirements of various high-temperature melting and heat treatment processes.
