Boron nitride plate introduction
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.
QS Advanced Materials Inc supplies custom made boron nitride discs and other machined products in about 2 weeks with $200 MOQ. Typical boron nitride crucible set has a crucible body and a staged boron nitride lid (lid with holes on it to balance pressure is available). Other forms could be available with drawings.

Dimension and cost estimation of boron nitride plates
Due to the limit of hot pressed boron nitride raw material, please notice our boron nitride discs has limits on dimensions.
Diameter/Width/Length < 16", 0.1"<thickness<8"*Enhanced composite boron nitride plates are usually available within 12"x12"x6".
For a quick estimation of price of your custom designed discs and other simple boron nitride shapes, pleas use the equations below
Price = Unit price x L. x W. x H.
*Current reference unit price for BN99 grade pure boron nitride: $34.40/inch3 ($2.10/cc)

Boron nitride plates packaging
As a ceramic material, boron nitride plates are quite fragile in a lot of cases. Our BN plates are usually hold in plastic bags by vacuum, and protect with heavy foam.
