Boron Nitride Ceramic and Components

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. > Matching materials: BN-99, BN-AL > Advantages: high temperature resistance (2000℃), thermal shock resistance, high electrical breakdown strength (3 -4 times that of alumina), carbon atmosphere corrosion resistance is much stronger than alumina > Used for polysilicon ingot furnace, graphitization heat treatment furnace, vacuum sintering furnace, atmosphere furnace ect. Grades 5 grades of boron nitrides are involved in Boron Nitride product series. * BN99 ● CABN ● ALBN ● ZRBN ● ZABN ● SB

Pyrolytic boron nitride is a grade of hexagonal boron nitride. It is produced by the chemical vapor deposition process to create its solid body and all the boron nitride crystals grow parallel to the surface on which the vapor is deposited.

Boron Nitride Specifications: >Outside Diameter: 6.40 mm >Inside Diameter: 1.70 mm >Wall Thickness: 2.35 mm >Length: 100 mm >Condition: Hot Pressed >Custom size is available. White in color. 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. Features of Boron Nitride: 1.High thermal conductivity 2.Low thermal expansion 3.Good thermal shock resistance 4.High electrical resistance 5.Low dielectric constant and loss tangent 6.Microwave transparency 7.Non toxic 8.Easily machined — non abrasive and lubricious 9.Chemically inert 10.Not wet by most molten metals

Alumina ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. In addition, it is extremely resistant to wear and corrosion and is an industrial ceramic that can only be formed by diamond grinding. The melting point is very high at 2,072°C, and it is very hard. Alumina components can be widely used in electronics, pump components and automotive sensors.
