What is boron nitride?
Boron nitride is typically black, brownish or dark red crystals with sphalerite structure and good thermal conductivity. Its solidity is second just to ruby, a superhard material frequently used as device products and also abrasives. Boron nitride has chemical resistance and also no disintegration by inorganic acid as well as water. The boron nitrogen bond is barged in hot, concentrated antacids. Oxidation starts in the air at 1200 ℃. Disintegration starts at regarding 2700 ℃ in a vacuum cleaner. It is somewhat soluble in warm acid and also insoluble in chilly water. The family member density is 2.29. The compressive stamina is 170 mph. The maximum service temperature level is 900 ℃ in the oxidation environment as well as 2800 ℃ in the non-active decrease atmosphere, but the lubrication efficiency is inadequate at room temperature. The majority of properties of boron nitride are much better than carbon products. For hexagonal boron nitride: the rubbing coefficient is shallow Good high-temperature stability, great thermal shock resistance, high toughness, high thermal conductivity, reduced development coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.
What is the duty of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, advanced refractories and also superhard material; splitting up rings for continual straight rolling, high-temperature resistant lubricants and high-temperature finishings. It is also a resources for synthesizing cubic boron nitride. Additionally, it is also a really outstanding high-temperature lubricating substance, which can be made use of as a part of self-lubricating bearings. Boron nitride has many physical properties similar to graphite, called white graphite. It resembles mica, talc, as well as silicate; Fatty acids are collectively referred to as white solid lubricating substances. As a lubricating substance, boron nitride can be distributed in heat-resistant lubricating grease, water or solvent; It is sprayed on the rubbing surface area to develop a dry film after the solvent volatilizes and afterwards filled out the resin, ceramic, and metal surface layers as a high-temperature immune self-lubricating composite product. It is used in aerospace engineering, or the boron nitride powder can be directly coated on the guide rail surface area. The boron nitride suspension oil is white or yellow. Therefore, it does not contaminate fiber products in fabric equipment and can be extensively made use of in the lubrication of synthetic fibre textile equipment.
Is Boron nitride unsafe to body?
Boron nitride is not hazardous, yet boron nitride powder is a cloud of dust damaging to human health and wellness. Boron nitride powder is physically inert as well as will be harmful to wellness when swallowed, inhaled, as well as exposured to the skin and eyes. Consuming or inhaling will cause skin, breathing system, and also kidney circulation disorders.
Cost of boron nitride
Boron nitride bit dimension as well as purity will affect the product'' s cost, and also the purchase quantity can additionally affect the cost of boron nitride. A large amount of big quantity will be lower. The cost of boron nitride can be located on our company'' s official internet site.
