Spare Hbn 99% Boron Nitride Bn Irregular Insulation Parts

Product Description

Boron Nitride Properties

To make solid shapes, hBN powders and binders are hot-pressed in billets up to 490mm x 490mm x 410mm at pressures up to 2000 psi and temperatures up to 2000°C. This process forms a material that is dense and easily machined and ready to use. It is available in virtually any custom shape that can be machined and has unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.

 

• Excellent thermal shock resistance
• High electrical resistivity - excluding aerosols, paints, and ZSBN
• Low density
• High thermal conductivity
• Anisotropic (thermal conductance is different in different planes relative to pressing direction)
• Corrosion resistant
• Good chemical inertness
• High temperature material
• Non-wetting
• High dielectric breakdown strength, >40 KV/mm
• Low dielectric constant, k=4
• Excellent machinability

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.
