Boron Nitride Nozzle Boron Nitride Ceramic Price Ceramic Parts
Application
Boron nitride ceramics can be used in the manufacture of high-temperature containers for metallurgical melting, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells, and glass forming dies.
Product Description
Boron nitride ceramic has good heat resistance, thermal stability, thermal conductivity and high temperature dielectric strength. It is an ideal heat dissipating material and high temperature insulating material. Boron nitride has good chemical stability and is resistant to most of the molten metal. It also has good self-lubricating properties. Boron nitride products have low hardness and can be machined with an accuracy of 1/100 mm.
