Hexagonal High Pressed Boron Nitride Ceramic Cylinder

BN is a material with non-wet feature. So molten metal won’t be sticked onto the nozzle. Additionally, Boron Nitride ceramic is a kind of refractory ceramic with low expansion and high thermal conductivity. These features make it to be an ideal choice as atomizing nozzles. It's very easy to be machined to custom design with precision and tight tolerance because of its machinability. Boron Nitride Ceramic BN Nozzles Performance: 1.The optimized formula and unigque process make it highly resistant to thermal shock and high-temperature creep.Maximum using temperature 1700°C. 2.Low thermal expansion coefficient,no cracking or deformation during use. 3.Strong erosion resistance,wear resistance and metal corrosion resitance.Long service life. 4.Good raw materials,process control,product stability. 5. It is used in Amorphous Ribbon Making and amorphous nozzles.

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
