Boron Nitride (H-BN) Disc
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 of demand for the customers. Check the boron nitride specifications for our pure BN99 and zirconia composite material ZSBN.

As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride 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.
