How heat resistant is boron nitride

What is boron nitride?
Boron nitride is typically black, brown or dark red crystals with sphalerite framework and also excellent thermal conductivity. Its firmness is 2nd only to diamond, a superhard product frequently utilized as device materials as well as abrasives. Boron nitride has chemical resistance and also no disintegration by not natural acid and water. The boron nitrogen bond is barged in hot, focused antacids. Oxidation starts airborne at 1200 ℃. Decomposition begins at concerning 2700 ℃ in a vacuum. It is slightly soluble in warm acid as well as insoluble in chilly water. The relative density is 2.29. The compressive stamina is 170 mph. The optimum solution temperature level is 900 ℃ in the oxidation ambience and 2800 ℃ in the non-active decrease environment, however the lubrication efficiency is poor at space temperature. Many buildings of boron nitride are better than carbon materials. For hexagonal boron nitride: the friction coefficient is shallow Great high-temperature security, great thermal shock resistance, high stamina, high thermal conductivity, reduced growth coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.

What is the function of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, progressed refractories and also superhard material; separation rings for constant horizontal rolling, high-temperature resistant lubricating substances as well as high-temperature finishes. It is likewise a raw material for manufacturing cubic boron nitride. Additionally, it is also a very superb high-temperature lubricant, which can be used as a component of self-lubricating bearings. Boron nitride has numerous physical residential or commercial properties comparable to graphite, called white graphite. It is similar to mica, baby powder, and also silicate; Fatty acids are jointly referred to as white solid lubricating substances. As a lube, boron nitride can be spread in heat-resistant lubricating grease, water or solvent; It is sprayed on the friction surface to form a completely dry movie after the solvent volatilizes and afterwards filled out the material, ceramic, and also 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 guide rail surface. The boron nitride suspension oil is white or yellow. As a result, it does not pollute fibre products in fabric equipment and also can be extensively used in the lubrication of synthetic fiber textile equipment.

Is Boron nitride hazardous to human body?
Boron nitride is not poisonous, yet boron nitride powder is a cloud of dirt damaging to human health. Boron nitride powder is physically inert as well as will be harmful to health when ingested, inhaled, as well as contacted with the skin and eyes. Consuming or breathing in will create skin, breathing system, and also kidney circulation disorders.

Cost of boron nitride
Boron nitride particle size as well as pureness will affect the product'' s price, and the purchase volume can additionally influence the expense of boron nitride. A huge quantity of huge quantity will be reduced. The cost of boron nitride can be discovered on our business'' s official web site.
