Innovacera 99 Bn Boron Nitride Evaporation Boat for Vacuum Coaters¹

Product Description Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100°. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from 1000 degree furnace and colding it within short minutes. It still won't break even repeat this test with 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 grades of boron nitrides are involved in Boron Nitride product series.* BN99 CABN ALBN ZRBN ZABN SB Applications1.
