How heat resistant is boron nitride
What is boron nitride?
Boron nitride is normally black, brownish or dark red crystals with sphalerite structure and also great thermal conductivity. Its solidity is 2nd just to diamond, a superhard material commonly utilized as tool materials and also 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, concentrated antacids. Oxidation begins in the air at 1200 ℃. Disintegration starts at regarding 2700 ℃ in a vacuum. It is a little soluble in warm acid as well as insoluble in cool water. The family member thickness is 2.29. The compressive toughness is 170 miles per hour. The optimum service temperature level is 900 ℃ in the oxidation atmosphere and also 2800 ℃ in the non-active decrease atmosphere, however the lubrication performance is poor at room temperature level. Many residential or commercial properties of boron nitride are better than carbon materials. For hexagonal boron nitride: the friction coefficient is superficial Good high-temperature security, good thermal shock resistance, high toughness, high thermal conductivity, low expansion coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.
What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, progressed refractories and also superhard material; separation rings for constant horizontal rolling, high-temperature immune lubricants as well as high-temperature coatings. It is additionally a resources for manufacturing cubic boron nitride. In addition, it is additionally a really outstanding high-temperature lubricant, which can be utilized as a component of self-lubricating bearings. Boron nitride has several physical homes similar to graphite, called white graphite. It is similar to mica, talcum powder, as well as silicate; Fatty acids are jointly referred to as white strong lubricating substances. As a lube, boron nitride can be spread in heat-resistant lubricating oil, water or solvent; It is splashed on the friction surface to develop a dry movie after the solvent volatilizes and after that filled in the resin, ceramic, and steel surface layers as a high-temperature immune self-lubricating composite product. It is utilized in aerospace engineering, or the boron nitride powder can be straight coated on the guide rail surface. The boron nitride suspension oil is white or yellow. Therefore, it does not pollute fiber items in fabric equipment as well as can be widely used in the lubrication of artificial fiber textile machinery.
Is Boron nitride dangerous to human body?
Boron nitride is not poisonous, yet boron nitride powder is a cloud of dust damaging to human health. Boron nitride powder is physically inert and will certainly be detrimental to wellness when swallowed, breathed in, and contacted with the skin and also eyes. Consuming or inhaling will create skin, breathing system, as well as kidney circulation disorders.
Price of boron nitride
Boron nitride fragment dimension and pureness will impact the product'' s cost, and also the purchase quantity can also affect the expense of boron nitride. A big quantity of huge quantity will certainly be reduced. The rate of boron nitride can be discovered on our company'' s main website.
