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. crucibles, can be frequently estimated based on the quantity of BN solid it consumed. 

 QS Rare Elements supplies custom made boron nitride crucibles 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).
