Boron nitride disc introduction
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.
QS Advanced Materials 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.

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.
Dimension and cost estimation of boron nitride discs
Due to the limit of hot pressed boron nitride raw material, please notice our boron nitride discs has limits on dimensions.

*Enhanced boron nitride discs are usually available within 12"x12"x12".
For a quick estimation of price of your custom designed discs and other simple boron nitride shapes, pleas use the equations below
|
Rectangular shape: Price = Unit price x max.L. x max.W. x max.H.
Cylinder shape: Price = Unit price x (max.OD.)2 x max.H.
*Current reference unit price for BN99 grade pure boron nitride: $34.40/inch3 ($2.10/cc) |

* HBN,HBC,BIN77...are originally a product code for another material supplier,Momentive Performance Materials. QSAM is also providing enhanced boron nitride/boron nitride composite material, e.g.calcium borate enhanced BNwith similar performance compared with HBN. Although calcium (or zirconium) enhanced HBN (or ZSBN) are the most common composite boron nitride material, we also produce a series of other composite boron nitride, such as AlN-BN, SiC-BN, which usually have better wear resistance, making it a better material to contact with molten meltal or insulators in PVD chamber (may need sand blast cleaning)

As a ceramic material, boron nitride is quite fragile in a lot of cases. The BN insulators are usually hold in plastic bags by vacuum, and protect with heavy foam.
