Hexagonal boron nitride

Hexagonal boron nitride

1. Product information

Product Name: Hexagonal boron nitride

Molecular Formula:BN

Molecular Weight: 24.82

Appearance: White crystal powder

2. Properties

Hexagonal boron nitride crystal structure similar to graphite layered structure, showing loose, smooth, easy to absorb moisture, light, and other traits of the white powder, the so called "white graphite." Theoretical density of 2.27g / cm3, Mohs hardness 2.

Point, nitrogen 0.1MPA 3000 ℃ sublimation, in an inert gas melting point 3000 ℃, the reduction in a neutral atmosphere, heat to 2000 ℃, temperature up to 2200 ℃ in nitrogen and argon, stability in an oxygen atmosphere poor, can be used to 900 ℃. Expansion coefficient of hexagonal boron nitride is equivalent to quartz, but quartz thermal rate of ten times.

Hexagonal boron insoluble in water, when water boils hydrolyzed very slowly and produce a small amount of boric acid and nitrogen; and weak acids and bases are not at room temperature, slightly soluble in hot acid, with molten sodium hydroxide, potassium hydroxide to decompose.

3. Packing

20kg drum, contains 2 plastic bags(10kg/bag), or by request of clients.

4. Transport storage

When transported, it should be in a clean, clean, covered wagon or boat.

Should be stored in a dry, clean, ventilated warehouse, not in the open air, not ship with strong oxidants

5. Application

(1)   A special electrolytic and resistance material under conditions of high temperature.

(2)  high-temperature solid lubricant, squeeze anti-wear additives, additive producing ceramic composite materials, refractories and antioxidant additives

(3)   transistors desiccant and heat-sealed plastic resins and other polymer additives

(4)   participation in the catalyst, the process can be converted to high temperature and pressure as hard as diamond cubic boron nitride.

(5)  all kinds of aluminum laser anti-counterfeit trademark gold foil materials, various enlarging, beer label, packaging, aluminum and so on cigarette packaging.

(6)  Cosmetic filler for lipstick, non-toxic but also lubricity, and glossy lipstick is the best in France
