How heat resistant is boron nitride

What is boron nitride?
Boron nitride is generally black, brown or dark red crystals with sphalerite framework and excellent thermal conductivity. Its hardness is 2nd only to ruby, a superhard product generally utilized as tool products and abrasives. Boron nitride has chemical resistance as well as no disintegration by not natural acid and water. The boron nitrogen bond is barged in hot, focused antacids. Oxidation starts airborne at 1200 ℃. Decomposition starts at regarding 2700 ℃ in a vacuum cleaner. It is slightly soluble in warm acid as well as insoluble in cold water. The family member density is 2.29. The compressive stamina is 170 miles per hour. The optimum solution temperature is 900 ℃ in the oxidation atmosphere and 2800 ℃ in the non-active decrease ambience, however the lubrication efficiency is bad at area temperature level. A lot of residential properties of boron nitride are far better than carbon materials. For hexagonal boron nitride: the rubbing coefficient is shallow Excellent high-temperature security, excellent thermal shock resistance, high toughness, high thermal conductivity, reduced 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, advanced refractories as well as superhard product; splitting up rings for constant horizontal rolling, high-temperature immune lubricants as well as high-temperature coverings. It is also a raw material for manufacturing cubic boron nitride. In addition, it is likewise a really exceptional high-temperature lube, which can be made use of as a part of self-lubricating bearings. Boron nitride has several physical properties similar to graphite, called white graphite. It is similar to mica, talc, and also silicate; Fatty acids are jointly described as white strong lubricants. As a lubricant, boron nitride can be spread in heat-resistant lubricating oil, water or solvent; It is sprayed on the friction surface area to create a dry film after the solvent volatilizes and then filled in the material, ceramic, and metal surface area layers as a high-temperature immune self-lubricating composite product. It is used in aerospace design, or the boron nitride powder can be straight coated on the guide rail surface area. The boron nitride suspension oil is white or yellow. As a result, it does not pollute fiber products in textile machinery and can be commonly used in the lubrication of synthetic fiber fabric equipment.

Is Boron nitride damaging to body?
Boron nitride is not hazardous, yet boron nitride powder is a cloud of dust damaging to human health. Boron nitride powder is physically inert and will certainly be harmful to health when ingested, breathed in, as well as exposured to the skin and also eyes. Consuming or inhaling will certainly create skin, breathing system, as well as kidney blood circulation problems.

Rate of boron nitride
Boron nitride particle dimension as well as purity will affect the item'' s rate, and also the acquisition quantity can additionally impact the price of boron nitride. A big quantity of huge quantity will certainly be reduced. The cost of boron nitride can be located on our business'' s official internet site.
