How heat resistant is boron nitride
What is boron nitride?
Boron nitride is usually black, brownish or dark red crystals with sphalerite structure and also great thermal conductivity. Its firmness is 2nd just to ruby, a superhard material generally used as device products and abrasives. Boron nitride has chemical resistance as well as no disintegration by not natural acid as well as water. The boron nitrogen bond is broken in warm, concentrated alkali. Oxidation begins airborne at 1200 ℃. Decomposition begins at regarding 2700 ℃ in a vacuum. It is somewhat soluble in hot acid and insoluble in chilly water. The family member density is 2.29. The compressive stamina is 170 mph. The maximum solution temperature is 900 ℃ in the oxidation ambience and also 2800 ℃ in the non-active reduction environment, but the lubrication performance is inadequate at area temperature level. Many properties of boron nitride are better than carbon materials. For hexagonal boron nitride: the friction coefficient is superficial Good high-temperature stability, good thermal shock resistance, high stamina, high thermal conductivity, low growth coefficient, high resistivity, corrosion resistance, microwave or infrared transmission.
What is the duty of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, progressed refractories and superhard material; splitting up rings for continual straight rolling, high-temperature immune lubes and high-temperature coatings. It is also a resources for manufacturing cubic boron nitride. Furthermore, it is also a very superb high-temperature lubricant, which can be used as a component of self-lubricating bearings. Boron nitride has lots of physical properties comparable to graphite, called white graphite. It is similar to mica, baby powder, as well as silicate; Fats are collectively referred to as white strong lubricants. As a lubricating substance, boron nitride can be spread in heat-resistant lubricating oil, water or solvent; It is splashed on the rubbing surface to create a dry movie after the solvent volatilizes and afterwards filled out the material, ceramic, and steel surface area layers as a high-temperature resistant self-lubricating composite product. 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. As a result, it does not pollute fiber products in textile equipment and can be widely used in the lubrication of synthetic fibre fabric equipment.
Is Boron nitride hazardous to body?
Boron nitride is not hazardous, however boron nitride powder is a cloud of dust unsafe to human health. Boron nitride powder is literally inert as well as will be detrimental to wellness when swallowed, breathed in, and also exposured to the skin and also eyes. Consuming or inhaling will certainly create skin, breathing system, and also kidney flow problems.
Rate of boron nitride
Boron nitride bit size and pureness will influence the item'' s price, and the purchase quantity can additionally affect the expense of boron nitride. A big amount of large amount will certainly be lower. The price of boron nitride can be located on our firm'' s official web site.
