Hexagonal boron nitride has good electrical insulation, thermal conductivity, chemical corrosion resistance and lubricity,It has strong neutron absorption capacity and is relatively stable to almost all organic solvents and corrosive chemicals，and is chemically inert to almost all molten metals. In the air below 900℃, the physical and chemical properties basically remain unchanged; In nitrogen or argon gas use temperature of 2800℃ can still maintain stability.
