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.
What is the duty of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, advanced refractories and also superhard product; separation rings for continuous horizontal rolling, high-temperature resistant lubes as well as high-temperature coverings. It is also a raw material for synthesizing cubic boron nitride. Additionally, it is also a really outstanding high-temperature lube, which can be made use of as a part of self-lubricating bearings. Boron nitride has lots of physical homes similar to graphite, called white graphite. It resembles mica, talcum powder, as well as silicate; Fats are jointly referred to as white strong lubricating substances. As a lube, boron nitride can be distributed in heat-resistant lubricating oil, water or solvent; It is sprayed on the friction surface to create a dry film after the solvent volatilizes and afterwards filled in the resin, ceramic, and also steel surface layers as a high-temperature resistant self-lubricating composite product. It is made use of in aerospace engineering, or the boron nitride powder can be directly coated on the overview rail surface area. The boron nitride suspension oil is white or yellow. Therefore, it does not pollute fiber products in textile equipment and can be widely made use of in the lubrication of artificial fibre fabric machinery.
