Boron Nitride Plate / Sheet Description

Boron nitride, or BN, is a chemical compound with equal numbers of boron and nitrogen atoms. The hexagonal form (HBN) corresponding to graphite is the softest and most stable form among BN polymorphs, and is therefore used as lubricant and an additive to cosmetic products. The cubic (CBN) variety analogous to diamond has high hardness which is inferior only to diamond. The rare wurtzite BN (WBN) modification is similar to lonsdaleite, and it may even be harder than CBN.

Boron Nitride Plate / Sheet Advantages

– Low wetability to molten metal
– Relatively high thermal conductivity with low thermal expansion
– Relatively high thermal shock resistance
– Extremely high working temperature with proper inert gas protection (>3000C has been recorded).

Boron Nitride Plate / Sheet Applications

-Electric insulators in vacuum system
-Insulators for high temperature furnace
-Spacers for glass melting
-Boron Nitride parts for ion injection equipment

Good Product

Use this bn plate to make gaskets for pouring spots on two 5 gallon gas jerry cans. Worked great used scalpel and fuel proof sealant - WALLA no leaking gas on HOT 9500 WATT Generator - Pleased

I bought some boron nitride ceramic materials months ago and I’m really impressed with ACM's good products and service. It helped my project get good results and it’s a very HIGH-PURITY material for the price.
