Boron Nitride Powder 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. 

Boron Nitride powders, also referred to as white graphite are non-abrasive, white powders with a hexagonal platy crystal structure similar to graphite, but with a much higher oxidation resistance at 800ºC. Boron Nitride ceramic powders have high thermal conductivity, low coefficient of friction, high dielectric constant and are chemically inert. Due to those unique properties Boron Nitride powders find use in a broad range of applications ranging from electronics, aerospace, oil and gas, ceramic manufacturing and cosmetics. 

Boron Nitride Powder 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 Powder Applications

Hexagonal boron nitride powder has been used:
– In the fabrication and luminescence study of monolayered boron nitride quantum dots.
– Rare earth boron complexes.
– Boron nitride filled polybenzoxazine system as a thermally conducting molding components for electronic packaging applications.
– Boron containing ceramic products.
– As a starting material to form BN nanotubes.
– To load silicone rubber and its consecutive effect on its thermal, mechanical and morphological properties was studied.

by Paul R. ONeil on Boron Nitride (BN) Powder

Works great for coating bullets! I add a liberal scoop (1/2tsp) to a tumbler with about 3 lbs of zinc coated bbs and 100 230gr rifle bullets, tumble for 12 hours, and then buff the bullets in a tube sock. Perfect pearlescent coating evenly over the whole bullet.

Everything was packed into a box into 3 separate smaller boxes and in the 3 smaller boxes each set was then packed again into individual boxes. The largest shipping box had some shipping air cushions. Everything seemed OK. Good.
