How heat resistant is boron nitride

What is boron nitride?
Boron nitride is usually black, brown or dark red crystals with sphalerite structure and great thermal conductivity. Its solidity is second only to ruby, a superhard material commonly utilized as device products and abrasives. Boron nitride has chemical resistance and also no disintegration by not natural acid and also water. The boron nitrogen bond is barged in hot, concentrated alkali. Oxidation starts airborne at 1200 ℃. Disintegration begins at regarding 2700 ℃ in a vacuum cleaner. It is slightly soluble in warm acid and insoluble in chilly water. The relative thickness is 2.29. The compressive toughness is 170 miles per hour. The maximum solution temperature is 900 ℃ in the oxidation atmosphere and 2800 ℃ in the non-active reduction ambience, but the lubrication efficiency is inadequate at area temperature. A lot of buildings of boron nitride are far better than carbon products. For hexagonal boron nitride: the friction coefficient is superficial Good high-temperature security, excellent thermal shock resistance, high toughness, high thermal conductivity, low expansion coefficient, high resistivity, corrosion resistance, microwave or infrared transmission.

What is the function of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, progressed refractories as well as superhard product; separation rings for continuous straight rolling, high-temperature immune lubricants and also high-temperature finishes. It is likewise a resources for manufacturing cubic boron nitride. On top of that, it is additionally a very outstanding high-temperature lubricant, which can be used as an element of self-lubricating bearings. Boron nitride has lots of physical residential properties comparable to graphite, called white graphite. It is similar to mica, talcum powder, and also silicate; Fatty acids are jointly referred to as white solid lubricating substances. As a lubricating substance, boron nitride can be spread in heat-resistant lubricating grease, water or solvent; It is splashed on the friction surface to develop a completely dry movie after the solvent volatilizes and then completed the resin, ceramic, as well as steel surface area layers as a high-temperature resistant self-lubricating composite product. It is used in aerospace design, or the boron nitride powder can be directly covered on the overview rail surface area. The boron nitride suspension oil is white or yellow. Therefore, it does not contaminate fiber items in textile machinery and also can be extensively used in the lubrication of synthetic fibre textile machinery.

Is Boron nitride unsafe to human body?
Boron nitride is not toxic, but boron nitride powder is a cloud of dirt hazardous to human wellness. Boron nitride powder is literally inert as well as will be detrimental to health when swallowed, inhaled, as well as contacted with the skin as well as eyes. Consuming or inhaling will create skin, breathing system, and also kidney blood circulation disorders.

Price of boron nitride
Boron nitride particle dimension as well as pureness will affect the item'' s price, as well as the purchase volume can likewise affect the expense of boron nitride. A large quantity of huge quantity will be lower. The cost of boron nitride can be found on our company'' s official site.
