Boron Nitride Disc (H-BN)
Diameter: 10~400mm, Thickness: >2mm
Boron Nitride Disc, H-BN Discs
We provide standard products & tailor-made products for hot-pressed boron nitride disc. Except for pure BN99 disc, we also supply BN composites with silicon carbide, calcium borate, aluminum nitride, and zirconia, to fulfill various demands of the customers. Check the boron nitride specifications for our pure BN99 and zirconia composite material ZSBN.

Packing
As a ceramic material, boron nitride is quite fragile in a lot of cases. Our h-BN ceramic disc is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
