How heat resistant is boron nitride

What is boron nitride?
Boron nitride is usually black, brown or dark red crystals with sphalerite structure and also good thermal conductivity. Its hardness is second just to diamond, a superhard product typically made use of as device materials and abrasives. Boron nitride has chemical resistance as well as no disintegration by inorganic acid and also water. The boron nitrogen bond is barged in hot, concentrated antacids. Oxidation begins airborne at 1200 ℃. Decay starts at about 2700 ℃ in a vacuum cleaner. It is a little soluble in hot acid and also insoluble in cold water. The family member density is 2.29. The compressive stamina is 170 mph. The maximum solution temperature level is 900 ℃ in the oxidation ambience and also 2800 ℃ in the non-active reduction ambience, but the lubrication efficiency is poor at area temperature. Many residential or commercial properties of boron nitride are far better than carbon materials. For hexagonal boron nitride: the friction coefficient is shallow Excellent high-temperature stability, great thermal shock resistance, high stamina, high thermal conductivity, reduced development coefficient, high resistivity, corrosion resistance, microwave or infrared transmission.

What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, progressed refractories and superhard material; splitting up rings for continuous straight rolling, high-temperature immune lubricants as well as high-temperature finishes. It is also a resources for manufacturing cubic boron nitride. Additionally, it is also a very superb high-temperature lube, which can be used as a part of self-lubricating bearings. Boron nitride has several physical homes comparable to graphite, called white graphite. It is similar to mica, talcum powder, and silicate; Fats are jointly described as white strong lubes. As a lubricating substance, boron nitride can be spread in heat-resistant lubricating grease, water or solvent; It is sprayed on the friction surface to create a completely dry film after the solvent volatilizes and afterwards filled out the resin, ceramic, and metal surface area layers as a high-temperature resistant self-lubricating composite material. It is utilized in aerospace engineering, or the boron nitride powder can be straight covered on the guide rail surface. The boron nitride suspension oil is white or yellow. For that reason, it does not pollute fiber products in fabric machinery as well as can be extensively utilized in the lubrication of synthetic fibre fabric machinery.

Is Boron nitride hazardous to human body?
Boron nitride is not harmful, but boron nitride powder is a cloud of dust harmful to human health. Boron nitride powder is physically inert and also will certainly be destructive to wellness when swallowed, inhaled, and exposured to the skin and eyes. Consuming or inhaling will certainly trigger skin, breathing system, and also kidney circulation problems.

Cost of boron nitride
Boron nitride bit dimension and pureness will affect the product'' s cost, and the purchase volume can also impact the cost of boron nitride. A huge quantity of large quantity will be lower. The cost of boron nitride can be discovered on our company'' s official web site.
