How heat resistant is boron nitride
What is boron nitride?
Boron nitride is typically black, brownish or dark red crystals with sphalerite structure as well as excellent thermal conductivity. Its solidity is 2nd just to diamond, a superhard product commonly made use of as tool products and abrasives. Boron nitride has chemical resistance as well as no erosion by not natural acid as well as water. The boron nitrogen bond is broken in warm, focused alkali. Oxidation begins in the air at 1200 ℃. Decay begins at about 2700 ℃ in a vacuum. It is somewhat soluble in hot acid as well as insoluble in cool water. The relative density is 2.29. The compressive toughness is 170 mph. The maximum solution temperature is 900 ℃ in the oxidation atmosphere as well as 2800 ℃ in the non-active reduction environment, but the lubrication performance is inadequate at space temperature. Most residential properties of boron nitride are far better than carbon materials. For hexagonal boron nitride: the friction coefficient is shallow Good high-temperature security, excellent thermal shock resistance, high strength, high thermal conductivity, low growth coefficient, high resistivity, rust resistance, microwave or infrared transmission.
What is the function of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, advanced refractories and also superhard material; splitting up rings for constant horizontal rolling, high-temperature resistant lubricants and also high-temperature finishes. It is additionally a raw material for synthesizing cubic boron nitride. Furthermore, it is additionally an extremely excellent high-temperature lubricating substance, which can be made use of as a component of self-lubricating bearings. Boron nitride has many physical residential properties comparable to graphite, called white graphite. It is similar to mica, baby powder, and silicate; Fatty acids are jointly referred to as white strong lubricants. As a lubricant, boron nitride can be distributed in heat-resistant lubricating oil, water or solvent; It is splashed on the friction surface to form a dry movie after the solvent volatilizes and afterwards filled in the material, ceramic, and metal surface layers as a high-temperature resistant self-lubricating composite material. It is made use of in aerospace design, or the boron nitride powder can be directly coated on the guide rail surface. The boron nitride suspension oil is white or yellow. Therefore, it does not contaminate fiber items in fabric equipment and also can be widely used in the lubrication of synthetic fibre textile machinery.
Is Boron nitride harmful to body?
Boron nitride is not hazardous, however boron nitride powder is a cloud of dust unsafe to human health and wellness. Boron nitride powder is physically inert and will certainly be harmful to wellness when swallowed, inhaled, and also exposured to the skin and also eyes. Consuming or breathing in will cause skin, respiratory system, and kidney blood circulation problems.
Cost of boron nitride
Boron nitride fragment dimension and purity will certainly affect the product'' s cost, and also the purchase quantity can also influence the expense of boron nitride. A large quantity of big amount will certainly be lower. The cost of boron nitride can be found on our business'' s main website.
