Product Description Hexagonal Boron Nitride has a microstructure similar to that of Graphite. In both materials, this structure, made up of layers of tiny platelets, is responsible for excellent machinability and low-friction properties. We called it hexagonal boron nitride (HBN) or white graphite.Boron nitride can be used long-term at 1800 °C under a vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100°. Boron Nitride has high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from a 1000-degree furnace and cool it within a short time. It still won't break even; repeat this test 100 times.Material Properties* High thermal conductivity* Excellent thermal shock resistance* Low thermal expansion* Exceptional heat resistance* Good Chemical Inertness* High electrical resistance* Low dielectric constant and loss tangent* High volume resistivity* Excellent machinabilityGrades 5 and 6 of boron nitrides are involved in the Boron Nitride product series.* BN99 CABN ALBN ZRBN ZABN SBApplications1.
