High Temperature Resistance Boron Nitride BN Ceramic Crucible
1.BN is made using a hot pressing process, and comes as a lubricious white solid. It can be machined using standard carbide drills. Due to crystal stucture, BN is anisotropic electrically and mechanically. BN exhibits a high electrical resistance, low dielectric constant and loss tangent, low thermal expansion, chemical inertness, and good thermal shock resistance.
2.Boron nitride is a unique material. it offers outstanding thermal conductivity, excellent dielectric strength, very good thermal shock resistance and is easily Machinable.

Boron nitride crystal belongs to the hexagonal crystal system, its structure is similar to that of graphite, and its performance has many similarities, so it is also called "white graphite". Boron nitride is a crystal composed of a nitrogen atom and a boron atom. The chemical composition is 43.6% boron and 56.4% nitrogen with four different variants: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) and wurtzite nitrogen. Boron (WBN).
Q: Is it possible to provide samples?
A: We can supply 1-2 samples, but we do not bear the shipping cost of the samples.
Q: How long is the delivery time usually?
A: Product delivery is subject to order quantity and processing requirements, and different product delivery times are inconsistent. Generally speaking, the delivery time of 1-2 common product samples is about 35 days.
Q: Which payment methods are supported?
A: T/T; credit card. Currently our company supports these two payment methods.
Q: What is the shipping date? How long can I ship?
