Product Overview


Products Description

Product Name
Corrosion resistant hollow boron nitride ceramic ring
High melting point, good thermal conductivity and insulation
It can be used for melting semiconductor and high-temperature container for metallurgy, heat dissipation insulating parts of semiconductor, high-temperature bearing, thermocouple sleeve and glass forming mould
working temperature
2000degree C

Boron Nitride ceramic are made by hot pressing hexagonal Boron Nitride powders. The color of BN products is milky, true density is 2.27g/cm, Mohs value is 2, they have a high melting point (sublimate point is 3000°C).

When in a condition of inert atmosphere,
their maximum service temperature can reach to 2800°C. Their thermal conductivity is 25W/(m·K), similar to stainless steel. And
coefficient of liner, and coefficient of liner expansion is between 2.0×10 /°C to 6.5×10 /°C.We can also customize it according to
your requirements.
