Product Description
Industrial Insulation Custom BN Boron Nitride Ceramic Tube
The specification of boron nitride ceramic tube
| 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 tube
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 material has high thermal stability, chemical stability and electrical insulation, but also has a high thermal conductivity, dielectric properties, and easy processing products and so on. Its melting point up to 2800 ℃, is a typical electrical insulator, but also an excellent thermal conductor.
We have been manufacturing various of boron nitride ceramic parts, including Boron nitride ceramic crucibles, Boron nitride ceramic setters, Boron nitride ceramic plates, Boron nitride ceramic rods, Boron nitride ceramic bushing and so on.
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.
