Boron Nitride Plate

hBN (CAS No.10043-11-5)is produced by hot pressing boron nitride powder/flake together into a solid material by sintering. It has low wettability to molten metal and some salts. Boron nitride is also the best high temperature electric insulator, with max. working temperature> 2000C in protective atmosphere.BN99 boron nirirde 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.As a result, boron nitride has wide applications in PVD coatings, high temperature furnace system and manufacturing of semicon materials.
Also, as a machinable ceramic material, boron nitride we are supplying could be machined into all kinds of custom designed shapes, as long as the raw material is big enough. Becuase the price for raw material (BN solid) is rather high(>$20/inch3), customers can estimate the price for simple shape products, e.g. plates based on the quantity of BN solid it consumed.
