What is boron nitride?
Boron nitride is usually black, brownish or dark red crystals with sphalerite framework and also great thermal conductivity. Its hardness is 2nd just to diamond, a superhard product typically utilized as tool materials as well as abrasives. Boron nitride has chemical resistance and no disintegration by not natural acid and water. The boron nitrogen bond is broken in warm, concentrated alkali. Oxidation begins in the air at 1200 ℃. Disintegration begins at about 2700 ℃ in a vacuum cleaner. It is somewhat soluble in hot acid as well as insoluble in cool water. The relative density is 2.29. The compressive stamina is 170 miles per hour. The optimum service temperature is 900 ℃ in the oxidation environment as well as 2800 ℃ in the non-active reduction ambience, yet the lubrication efficiency is bad at room temperature. Most properties of boron nitride are better than carbon products. For hexagonal boron nitride: the rubbing coefficient is shallow Excellent high-temperature security, excellent thermal shock resistance, high toughness, high thermal conductivity, low growth coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.
