Boron Nitride Rod Description

Boron nitride, or BN, is a chemical compound with equal numbers of boron and nitrogen atoms. The hexagonal boron nitride (HBN) corresponding to graphite is the softest and most stable form among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products. The cubic (CBN) variety analogous to diamond has a 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 Rod Advantages

BN rod is easily machinable. It has high performances:

– Low wetability to molten metal
– Low dielectric constant
– Relatively high dielectric strength
– 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).
– Chemical Vapor Deposition (CVD)
