Boron Nitride is one of technical synthetic ceramic material. It offer a unique combination of properties from high heat capacity and outstanding thermal conductivity to easy machinability, lubricity, low dielectric constant and superior dielectric strength .
Boron nitride ceramic parts widely used as ceramic insulators for high-temperature furnaces, side dams in thin-strip casting process, crucibles and containers for molten metals and break rings in horizontal continuous casting.
