Boron Nitride Crucible 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 Crucible 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 Crucible Applications

Boron Nitride ceramic from Advanced Ceramic Materials (ACM) can withstand high temperature in the high vacuum environment, plus it has excellent corrosion resistance and electrical resistance. Thus, Boron Nitride ceramic product is an ideal choice in a wide range of industries, such as:
– Crucibles for crystal growth
– Break rings for horizontal casting machine
– Insulators for high temperature furnace
– Electric insulators in vacuum system
– Feed through for high voltage equipment
