BN / pyrolytic boron nitride ceramic
- 99,5% BN / 96% BN -
Pyrolytic boron nitride is known for its direction-dependent thermal conductivity and optimal "heat distribution" to achieve uniform temperatures. Thanks to its thermal shock resistance, pyrolytic boron nitride is an excellent sealant and protects graphite from corrosive atmospheres such as. a. most molten metals, acids and hot ammonia. Pyrolytic boron nitride has also been shown to have extremely effective electrical insulating properties.
