Hexagonal boron nitride is a typical non-oxide ceramic material whose crystal structure is very similar to carbon. It has excellent heat resistance, low thermal expansion coefficient, good corrosion resistance, high thermal conductivity, excellent lubricity and chemical stability. Even at extremely high temperatures, the hexagonal boron nitride coating protects its unique resistance to metal or graphite corrosion and oxidation. Therefore, hexagonal boron nitride can be used for the protection of various refractory materials, and can also be used as raw and auxiliary materials for various waterproof materials, coating technologies and process applications.
