What is boron nitride?
Boron nitride is generally black, brownish or dark red crystals with sphalerite framework and also good thermal conductivity. Its firmness is second only to diamond, a superhard material frequently utilized as device products and abrasives. Boron nitride has chemical resistance as well as no disintegration by not natural acid and also water. The boron nitrogen bond is barged in hot, focused antacids. Oxidation starts in the air at 1200 ℃. Disintegration begins at about 2700 ℃ in a vacuum. It is a little soluble in warm acid as well as insoluble in cold water. The relative density is 2.29. The compressive strength is 170 mph. The optimum solution temperature is 900 ℃ in the oxidation environment and 2800 ℃ in the non-active decrease atmosphere, but the lubrication efficiency is bad at area temperature. The majority of properties of boron nitride are much better than carbon products. For hexagonal boron nitride: the rubbing coefficient is shallow Good high-temperature security, excellent thermal shock resistance, high toughness, high thermal conductivity, reduced growth coefficient, high resistivity, corrosion resistance, microwave or infrared transmission.

What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, progressed refractories and also superhard product; separation rings for continuous horizontal rolling, high-temperature resistant lubricating substances and high-temperature coatings. It is likewise a basic material for manufacturing cubic boron nitride. On top of that, it is likewise a very excellent high-temperature lube, which can be made use of as a part of self-lubricating bearings. Boron nitride has many physical properties similar to graphite, called white graphite. It resembles mica, baby powder, and silicate; Fats are collectively referred to as white solid lubes. As a lube, boron nitride can be distributed in heat-resistant lubricating oil, water or solvent; It is splashed on the rubbing surface to create a dry film after the solvent volatilizes and after that completed the resin, ceramic, as well as steel surface area layers as a high-temperature immune self-lubricating composite product. It is utilized in aerospace design, or the boron nitride powder can be straight covered on the guide rail surface. The boron nitride suspension oil is white or yellow. For that reason, it does not pollute fiber products in textile equipment and also can be extensively used in the lubrication of artificial fibre textile machinery.

Is Boron nitride hazardous to human body?
Boron nitride is not poisonous, yet boron nitride powder is a cloud of dirt unsafe to human wellness. Boron nitride powder is literally inert and also will certainly be harmful to health and wellness when swallowed, inhaled, and contacted with the skin and eyes. Consuming or breathing in will trigger skin, breathing system, as well as kidney blood circulation conditions.

Price of boron nitride
Boron nitride fragment size and also purity will influence the product'' s cost, and also the purchase volume can likewise impact the cost of boron nitride. A huge amount of large quantity will be lower. The rate of boron nitride can be located on our business'' s official web site.
