Boron nutride is composed of both nitrogen and boron. You can divide the crystal structure into hexagonal Boron Nitride (HBN), closely packed hexagonal Boron Nitride , and cubic Boron Nitride.
The hexagonal boron-nitride crystal has the same graphite layered structures as graphite. This gives it its name “white graphite”. Theoretical density: 2.27g/cm3, specific gravity: 2.43, Mohr Hardness = 2.
Hexagonalboron nitride is good at electrical insulation, thermal conductivity and chemical stability. Although hexagonal boron-nitride has the same expansion coefficient as quartz, its thermal conductivity exceeds that of quartz by tenfold.
Hexagonalboron nitride is not able to dissolve cold water. The water boils slowly, producing a very small amount of ammonia and boric acids. It is not soluble in hot acids and cannot be broken down with potassium hydroxide and molten sodium hydroxide.
Boron Nitride Properties
1. The heat resistance is high: Sublimation at 3000 at 1800. This strength can also be air-cooled at 1500 to ambient temperature for several dozens of time and not softens at 2800 in inert gases.
2. High thermal conductivity. The hot-pressed products behave the same way as pure iron. And 33W/M.K’s thermal conductivity is higher than that of ceramic materials at 530C.
3, Low thermal expansion coefficient. The thermal shock resistance of ceramics is excellent due to its low expansion coefficient (2 x 10-6).
4. It has excellent electrical characteristics: it is good at insulation at high temperatures (1014 O-cm.2000 at 25 and 1033 O-cm. It’s the most efficient ceramic high-temperature insulating material, with a breakdown voltage 3.0V/MV, low loss of 108HZ 2.5 x 10.4, dielectric constant 4., transparent to microwave and ultraviolet.
5. Excellent corrosion resistance: It does not react to iron, copper or aluminum. It is compatible with rare earth metals and precious metals as well as semiconductor materials (germanium-siliconium, potassium arsenide), glass and molten salts (crystals, fluoride, or slag), inorganic acids, and alkali.
6. Low friction coefficient U of 0.16. This is lower than the U for molybdenum disulfide or graphite. You can use oxidation atmosphere up to 900C and vacuum at 2000.
7. The purity of high purity B is very high. Its impure content is below 10PPM and its content in B is greater than 43.6%.
8. Machinability: Its hardness is Morse 2. This allows it to be machined into precise parts using general machining.
