What is it?

Boron Nitride (BN)?

Boron nitride (BN)

Refractory compounds of boron, nitrogen that are both thermally and chemically stable. It is available in different structures like the hexagonal (h-BN), cubic (c-BN), or wurtzite (w-BN) BNs.

General Properties of

Boron Nitride (BN)

1. Chemically resistant to water and inorganic acid attack

2. It is slightly soluble in hot acids, but insoluble when dissolved in cold water.

3. The maximum operating temperature for oxidizing and inactive reducing atmospheres is 900F.

4. Many properties of boron Nitride are better than those of carbon material.

5. Hexagonal Boron Nitride has a very low friction coefficient and good thermal shock resistance. It also has high strength, high thermal conductivity and low expansion coefficient.

Boron Nitride (BN)

1. Metal forming release agents and metal wire-drawing lubricant.

2. Special electrolytic and resistance materials for high temperatures.

3. High temperature solid oils, extrusion-anti-wear additives. Additives for the production ceramic composite materials.

4. Additives in polymer like plastic resin and heat sealing desiccant from Transistor

5. Boron nitride can be pressed into many shapes to be used as insulation, heat dissipation and high temperature pressure products.

6. Heat shielding materials for aerospace.

7. Cubic boron Nitride can be made by heating it and adding catalyst. It is almost as hard as diamond.

8. Structural materials needed for atomic reactors.

9. Aircraft, rocket engine nozzle.

10. Insulators for plasma arc and high voltage, high frequency electricity.

11. Material packaging that shields against neutron radiation

12. Material made from boron Nitride is extremely hard and can be used in high-speed cutters, geological exploration, drilling, etc.

13. Separation rings used for continuous casting of steel, amorphous-iron flow notch and continuous casting aluminium release agent (various optic glass release agent).

14. Protective package for freshness from aluminized.

15. Laser anti-counterfeiting aluminiu plating, trademark bronze materials, cigarette labels and beer labels, packaging boxes, aluminum plating for cigarette boxes, etc.

16. Cosmetics like lipstick filler, are non-toxic and lubricious. They also shine.
