Product Information

 

BORON NITRIDE POWDER


 

Boron nitride is a type of crystal made up of nitrogen atom and boron atom. Its crystal structure is HBN, WBN and cubic boron nitride. The crystal structure of HBN, similar to graphite layer, is loose, lubricative white powder that can easily absorb moisture and is light in weight, hence the name “white graphite”. Its theoretical density: 2.27g/cm3, specific gravity:2.43, Mullite hardness:2. HBN shows desirable insulativity and thermal conductivity, stable chemical property and without sharp melting point. When mixing with 0.1MPA nitrogen, it can resist heat of 3000℃; when in neutral reducing atmosphere,it can resist heat of 2000℃; when used in nitrogen and argon, the application temperature can be 2800℃. HBN shows poorstability when in oxygen and the usage temperature is below 1000℃. The dilatation coefficient of HBN is the same as that of quartz, but its thermal conductivity is ten times that of quartz.
HBN is insoluble in cold water. When boiled in water, its hydrolyzation process is very slow and will generate a small amount of boric acid and ammonia. It will not react with weak acid and alkali in indoor temperature and is slightly soluble in hot acid. Besides, it can resolve when treated with molten sodium hydroxide and potassium hydroxide.

 

HBN is one of advanced ceramic materials with hexagonal crystal structure. It can be used to produce TiB2/BN composite ceramic and can also be applied to high-grade refractory and superhard material. It also can be used as high-temperature lubricant, high-temperature paint, thermal conductive filter for LED and the raw material of synthetic cubic boron nitride. 

 

Suntek supplies a full series of HBN Powder, Spherical BN, and Nano BN spheres.
