How heat resistant is boron nitride

What is boron nitride?
Boron nitride is usually black, brown or dark red crystals with sphalerite framework and also great thermal conductivity. Its hardness is second just to ruby, a superhard product frequently used as tool products and abrasives. Boron nitride has chemical resistance as well as no erosion by inorganic acid and also water. The boron nitrogen bond is barged in warm, focused alkali. Oxidation starts in the air at 1200 ℃. Decomposition starts at about 2700 ℃ in a vacuum cleaner. It is somewhat soluble in hot acid as well as insoluble in cool water. The loved one density is 2.29. The compressive toughness is 170 miles per hour. The maximum service temperature is 900 ℃ in the oxidation ambience as well as 2800 ℃ in the non-active decrease environment, however the lubrication performance is poor at room temperature. The majority of homes of boron nitride are much better than carbon materials. For hexagonal boron nitride: the friction coefficient is superficial Great high-temperature security, great thermal shock resistance, high strength, high thermal conductivity, low growth coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.

What is the duty of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, advanced refractories as well as superhard product; separation rings for continual horizontal rolling, high-temperature immune lubes as well as high-temperature layers. It is additionally a raw material for synthesizing cubic boron nitride. In addition, it is also a really superb high-temperature lubricating substance, which can be used as a part of self-lubricating bearings. Boron nitride has numerous physical buildings similar to graphite, called white graphite. It is similar to mica, baby powder, and silicate; Fatty acids are jointly referred to as white strong lubricating substances. As a lubricant, boron nitride can be spread in heat-resistant lubricating grease, water or solvent; It is sprayed on the friction surface to develop a completely dry movie after the solvent volatilizes and then completed the resin, ceramic, and steel surface area layers as a high-temperature immune self-lubricating composite material. It is made use of in aerospace engineering, 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 pollute fibre items in fabric equipment as well as can be extensively made use of in the lubrication of synthetic fibre textile machinery.

Is Boron nitride harmful to body?
Boron nitride is not harmful, however boron nitride powder is a cloud of dust harmful to human wellness. Boron nitride powder is physically inert and also will certainly be destructive to health and wellness when ingested, inhaled, and also contacted with the skin as well as eyes. Consuming or inhaling will trigger skin, breathing system, and also kidney blood circulation disorders.

Rate of boron nitride
Boron nitride bit dimension as well as purity will influence the item'' s cost, as well as the purchase volume can also impact the expense of boron nitride. A big quantity of large amount will be reduced. The rate of boron nitride can be found on our business'' s main website.
