Hexagonal boron nitride HBN heat conducting powder
Product Description
Hexagonal boron nitride, H - BN, the structure is similar to that of graphite, also called "white graphite", it is the most widely used form of boron nitride.Like graphite, hexagonal forms are made up of many hexagons.The correlation between these layers is different, but from the pattern of graphite arrangement, it is due to the boron atoms on top of the nitrogen atoms that make the boron nitride atoms elliptical.Such a structure reflects the polarity of boron-nitrogen chains.
Hexagonal boron nitride in low and high temperature (900 ° C) even under oxygen is a kind of very good lubricant, due to its lubrication mechanism does not involve thewater moleculesbetween the layers, boronnitride lubricant can also be used in vacuum, such as when working in space.
Hexagonal boron nitride is still stable at up to 1000 ° C in the air, 1400 ° C invacuumand 2800 ° C in the inert gas, and it is one of theinsulators with best thermal conductivity.It has no chemical reaction to most substances and is not wet by many melting substances (e.g., aluminum, copper, zinc, iron and steel, chromium, silicon, boron, cryolite, glass and halogen).Ultrafine HBN is used in pigments, fillers and pencil reels.
The boron nitride produced by our company Hongwu nano has particle sizes of 100-200nm, 300-500nm, 800-1000nm, 1um, 5um and purity of 99.8%.With high activity and less impurity, the product quality is very stable.Hexagonal boron nitride is a good conductor of heat and good lubrication.
