Product Description

 

High purity 99.99% PBN pyrolytic boron nitride ceramic part

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.
Hot pressed BN is compacted at temperatures up to 2000°C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined. It is available in standard and custom hot pressed shapes and has several unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.

The products series include kinds of new materials such as structural products and functional ceramic products, such as Alumina, Aluminum Nitride, Zirconia, Silicon Nitride and Boron Nitride ceramics are the main products in the list. Zirconia derivative products such as high purity zirconia, Yttria stabilized zirconia(YSZ or Y-TZP), and Magnesia stabilized Zirconia(MgO-PSZ), and Ceria stabilized Zirconia(CeO-PSZ), structural zirconia ceramics, etc. For the zirconia products have many excellent properties such as high hardness, high strength and toughness, super low chemical and mechanical corrosive, insulated in common temperature, and magnetic proofing, so they are extensively applied in optic, electronic, mechanical and chemical industry, etc. And Alumina ceramics is more widely applied in industrial.
