How heat resistant is boron nitride

What is boron nitride?
Boron nitride is usually black, brown or dark red crystals with sphalerite framework and great thermal conductivity. Its hardness is second just to ruby, a superhard material typically made use of as tool materials as well as abrasives. Boron nitride has chemical resistance and no erosion by not natural acid as well as water. The boron nitrogen bond is broken in warm, concentrated alkali. Oxidation begins in the air at 1200 ℃. Decomposition starts at about 2700 ℃ in a vacuum. It is somewhat soluble in warm acid and insoluble in cold water. The relative density is 2.29. The compressive strength is 170 miles per hour. The maximum solution temperature is 900 ℃ in the oxidation atmosphere and 2800 ℃ in the non-active decrease atmosphere, 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 superficial Great high-temperature security, great thermal shock resistance, high stamina, high thermal conductivity, reduced 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 ceramics, progressed refractories as well as superhard product; separation rings for constant horizontal rolling, high-temperature resistant lubricants as well as high-temperature coatings. It is also a basic material for synthesizing cubic boron nitride. Furthermore, it is also a very excellent high-temperature lubricant, which can be used as a component of self-lubricating bearings. Boron nitride has several physical buildings similar to graphite, called white graphite. It resembles mica, baby powder, and silicate; Fatty acids are jointly described 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 rubbing surface to develop a completely dry film after the solvent volatilizes and after that filled in the material, ceramic, as well as metal surface area layers as a high-temperature resistant self-lubricating composite material. It is made use of in aerospace engineering, or the boron nitride powder can be directly coated on the overview rail surface. The boron nitride suspension oil is white or yellow. Therefore, it does not contaminate fibre products in fabric machinery as well as can be widely made use of in the lubrication of synthetic fibre textile equipment.

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

Cost of boron nitride
Boron nitride bit dimension as well as pureness will certainly influence the item'' s rate, and the purchase quantity can likewise influence the expense of boron nitride. A huge amount of big amount will certainly be reduced. The cost of boron nitride can be discovered on our firm'' s official web site.
