Boron Nitride InsulatorHigh-purity insulator for extreme heat and voltage.
The operating temperature can be up to 1900°C in vacuum, 2100°C in inert gas shielding (nitrogen, argon), and the oxidation temperature in air is usually about 900-1000°C (one reference gives 800°C). Some grades of boron nitride may have differing temperature limits. The difference in temperature limits under different atmospheres implies that the application environment is important when consideration is being given to using boron nitride plates.
Boron Nitride plates can be made as thin as 1 to 2 mm, depending on the application requirement.
They should be preserved in a clean, dry area, remote from mechanical stress and dampness, preferably packed within their original wrappings. Vacuum-blister packaging is preferred to prevent the uptake of moisture.
No, Boron Nitride plates are inert to most molten metals chemically and non-wetting and therefore optimally suitable as crucibles and liners for use in metalworking.
