Product Description

99% BN Ceramic Hexagonal Boron Nitride Plate

The specification of boron nitride plate

Purity over 99%
Max. dimensions available OD to be 300mm, length to be 400mm
The grade of tolerance General tolerance: 1% of the dimensions, 0.01mm after grinding

The main features of the boron nitride ceramic plate

1) BN is an easier machining advanced ceramic than the others, it can achieve the accuracy of 0.01mm;
2) The dielectric strength is 2300V/cm, which is 8 times that of Al2O3; RT resistivity at 1000ºC>10-7 Ω.cm;
3) Excellent thermal shock resistance, recover one hundred times from 20ºC to 1000ºC without damage;
4) For common metals (iron, copper, aluminum, lead, etc.), rare earth metals, precious metals, semiconductor materials (germanium, silicon, potassium arsenide), glass, molten salts (crystallite, fluoride, slag), inorganic acids, Alkali does not react.

The description of Boron Nitride Ceramics

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 .

The application of boron nitride ceramics

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.
