Boron Nitride Structural parts for PVD Sputtering Systems

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 hexagonal boron nitride (HBN) or white graphite. Material of Boron Nitride Ceramics: Pyrolytic Boron Nitride: 99.99% Boron Nitride* 99 Boron Nitride: Boron Nitride + Boric Oxide (B2O3) CABN: Boron Nitride + Calcium Borate ALBN: Boron Nitride + Al2BO3 ZRBN: Boron Nitride + Zirconium Oxide + Boric Oxide (B2O3) ZABN: Boron Nitride + Zirconium Oxide + Aluminum Nitride + Al2BO3 SCBN: Boron Nitride + Silicon Carbon + Al2BO3 Processing of Boron Nitride Ceramics: 1.Hot Pressed Sintering 2.Chemical Vapor Deposition

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 hexagonal boron nitride (HBN) or white graphite. 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 machinability

Mo Mn Ceramic Feedthrough Ceramic Vacuum Electrodes The Ceramic Surfaces for Brazing, the surface must be metallized. Compare to Glass seal, Ceramic seal has exceptional resistance to thermal and mechanical shock as well as corrosion. While it requires more complex manufacturing processes and sophisticated engineering, the price is obviously higher. Advantages of Ceramic-to-Metal Seals * More solid, durable hermetic seal and better electrical insulation * Used for more harsh conditions, such as high and low (cryogenic) temperature, corrosive, high pressure, and high vacuum environments * High mechanical strength, less fracture when applied to high vibration and high g-load conditions * Shows strong bond and an excellent seal with metals and alloys, such as copper and Cu alloys (CuNi) and to nickel and Ni alloys.
