How heat resistant is boron nitride

What is boron nitride?
Boron nitride is typically black, brown or dark red crystals with sphalerite framework and great thermal conductivity. Its solidity is 2nd just to diamond, a superhard product frequently used as tool materials as well as abrasives. Boron nitride has chemical resistance and also no erosion by not natural acid as well as water. The boron nitrogen bond is barged in hot, concentrated alkali. Oxidation starts in the air at 1200 ℃. Disintegration starts at regarding 2700 ℃ in a vacuum. It is slightly soluble in hot acid and also insoluble in cool water. The relative thickness is 2.29. The compressive strength is 170 mph. The optimum service temperature is 900 ℃ in the oxidation environment as well as 2800 ℃ in the non-active decrease atmosphere, however the lubrication efficiency is inadequate at room temperature. Many homes of boron nitride are much better than carbon materials. For hexagonal boron nitride: the rubbing coefficient is superficial Great high-temperature security, good thermal shock resistance, high toughness, high thermal conductivity, low expansion 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, progressed refractories and also superhard product; splitting up rings for constant horizontal rolling, high-temperature resistant lubricants and also high-temperature coatings. It is likewise a basic material for manufacturing cubic boron nitride. In addition, it is also a really excellent high-temperature lube, which can be made use of as a component of self-lubricating bearings. Boron nitride has many physical residential properties similar to graphite, called white graphite. It resembles mica, baby powder, as well as silicate; Fatty acids are collectively referred to as white solid lubes. As a lubricant, boron nitride can be distributed in heat-resistant lubricating grease, water or solvent; It is sprayed on the friction surface area to develop a dry film after the solvent volatilizes and then filled in the material, ceramic, as well as metal surface layers as a high-temperature immune self-lubricating composite material. It is made use of in aerospace design, or the boron nitride powder can be directly coated on the overview rail surface. The boron nitride suspension oil is white or yellow. For that reason, it does not contaminate fibre items in fabric machinery as well as can be widely used in the lubrication of artificial fiber fabric equipment.

Is Boron nitride dangerous to body?
Boron nitride is not toxic, but boron nitride powder is a cloud of dirt harmful to human health. Boron nitride powder is physically inert and will be damaging to health and wellness when ingested, inhaled, and exposured to the skin and also eyes. Consuming or breathing in will certainly cause skin, respiratory system, as well as kidney circulation problems.

Rate of boron nitride
Boron nitride particle dimension as well as pureness will certainly impact the product'' s price, as well as the acquisition quantity can additionally impact the price of boron nitride. A huge quantity of huge amount will certainly be lower. The price of boron nitride can be discovered on our company'' s main website.
