Boron Nitride Disc

hBN is produced by sinter the boron nitride powder together into a solid material, usually an approximately 1ft cube or cylinder. As a machinable material material, HBN boron nitride we supplied could be machined into all kinds of customized shapes, as long as the raw material is big enough. As the price for raw material (BN solid) is rather high(>$20/inch3), price for simple shape products, e.g. discs, can be frequently estimated based on the quantity of BN solid it consumed.
BN99 material we provided had record to work smoothly with 3500C gas flow in inert gas but the long term evironment temperature should be kept below 2200C according to the high temperature survival tests. In vaccum, the discs could only withstand 1900C, as it decompose before m.p.
Due to the limit of hot pressed boron nitride raw material, please notice our boron nitride discs has limits on dimensions.
