The description of boron nitride ceramic rod

Boron nitride ceramic is resistant to chemical corrosion, like variety acids and alkalis. Besides, it offers strong electrical insulation with an electrical breakdown strength of 3-4 times that of alumina. Moreover, BN ceramics possess excellent high temperature resistance.

The use temperature is 1800 degrees under vacuum, and the use temperature is 2200 degrees under the protection of atmosphere(nitrogen, argon and other inert gases). The boron nitride ceramic has a high thermal conductivity, strong thermal shock resistance, and does not crack when quenched at 1500 degrees. It is taken out of the furnace at a temperature of 1000 degrees for 20 minutes, and then blown and quenched for hundreds of times without cracking. Boron Nitride Ceramics do not react and do not adhere to many metals, ceramics, rare earths and other materials.

We have been providing numerous Boron nitride ceramic products, including boron nitride ceramic rod, Boron nitride ceramic tube, boron nitride ceramic plates, boron nitride ceramic nozzle. With our 15-year manufacturing experience of OEM, ODM, we also have the production lines for alumina ceramics and zirconia ceramics.
