How heat resistant is boron nitride
What is boron nitride?
Boron nitride is normally black, brownish or dark red crystals with sphalerite framework as well as great thermal conductivity. Its firmness is second only to diamond, a superhard product generally made use of as tool materials and abrasives. Boron nitride has chemical resistance and also no erosion by not natural acid as well as water. The boron nitrogen bond is broken in warm, focused antacids. Oxidation starts airborne at 1200 ℃. Decomposition begins at about 2700 ℃ in a vacuum. It is somewhat soluble in hot acid as well as insoluble in cool water. The relative density is 2.29. The compressive strength is 170 miles per hour. The optimum solution temperature level is 900 ℃ in the oxidation ambience as well as 2800 ℃ in the non-active reduction environment, yet the lubrication performance is inadequate at room temperature level. The majority of homes of boron nitride are better than carbon products. For hexagonal boron nitride: the friction coefficient is shallow Excellent high-temperature stability, good thermal shock resistance, high stamina, high thermal conductivity, low expansion coefficient, high resistivity, corrosion resistance, microwave or infrared transmission.
What is the function of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, advanced refractories and also superhard material; splitting up rings for continual horizontal rolling, high-temperature immune lubes and also high-temperature coverings. It is additionally a raw material for manufacturing cubic boron nitride. Furthermore, it is likewise an extremely outstanding high-temperature lube, which can be made use of as a component of self-lubricating bearings. Boron nitride has many physical properties similar to graphite, called white graphite. It is similar to mica, talc, as well as silicate; Fatty acids are collectively described as white solid lubricating substances. As a lubricating substance, boron nitride can be dispersed in heat-resistant lubricating grease, water or solvent; It is sprayed on the friction surface area to develop a dry film after the solvent volatilizes and then completed the resin, ceramic, as well as steel surface layers as a high-temperature resistant self-lubricating composite product. It is utilized in aerospace design, or the boron nitride powder can be directly coated on the guide rail surface area. The boron nitride suspension oil is white or yellow. As a result, it does not contaminate fiber items in textile machinery as well as can be commonly utilized in the lubrication of artificial fiber fabric equipment.
Is Boron nitride unsafe to human body?
Boron nitride is not toxic, but boron nitride powder is a cloud of dust unsafe to human health. Boron nitride powder is physically inert and also will certainly be destructive to wellness when swallowed, breathed in, and also exposured to the skin as well as eyes. Consuming or breathing in will trigger skin, breathing system, as well as kidney blood circulation conditions.
Price of boron nitride
Boron nitride bit size and purity will impact the item'' s cost, and also the acquisition volume can additionally influence the expense of boron nitride. A big quantity of large quantity will be reduced. The cost of boron nitride can be found on our business'' s main website.
