Hexagonal boron nitride can withstand 900 C , has high thermal conductivity, has low expansion ratio and is advanced ceramic materials which it has good lubrication properties at elevated temperature. One of the most important characteristics of hexagonal boron nitride is that it has low wettability by molten metals and slags.
