How heat resistant is boron nitride

What is boron nitride?
Boron nitride is usually black, brown or dark red crystals with sphalerite structure and great thermal conductivity. Its hardness is second just to ruby, a superhard material generally used as device products as well as abrasives. Boron nitride has chemical resistance as well as no erosion by not natural acid as well as water. The boron nitrogen bond is barged in hot, focused antacids. Oxidation begins in the air at 1200 ℃. Disintegration starts at about 2700 ℃ in a vacuum. It is a little soluble in warm acid and insoluble in chilly water. The loved one thickness is 2.29. The compressive stamina is 170 miles per hour. The maximum solution temperature is 900 ℃ in the oxidation ambience as well as 2800 ℃ in the non-active reduction ambience, yet the lubrication efficiency is bad at room temperature level. The majority of residential or commercial properties of boron nitride are far better than carbon products. For hexagonal boron nitride: the rubbing coefficient is superficial Excellent high-temperature stability, good thermal shock resistance, high stamina, high thermal conductivity, reduced development coefficient, high resistivity, rust resistance, microwave or infrared transmission.


What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite porcelains, progressed refractories and superhard product; splitting up rings for continuous horizontal rolling, high-temperature immune lubes and also high-temperature finishes. It is likewise a basic material for manufacturing cubic boron nitride. On top of that, it is likewise a really exceptional high-temperature lubricant, which can be utilized as an element of self-lubricating bearings. Boron nitride has many physical residential or commercial properties comparable to graphite, called white graphite. It resembles mica, talc, and silicate; Fats are collectively referred to as white strong lubes. As a lubricating substance, boron nitride can be dispersed in heat-resistant lubricating oil, water or solvent; It is sprayed on the rubbing surface area to develop a completely dry film after the solvent volatilizes and then completed the material, ceramic, and metal surface layers as a high-temperature resistant self-lubricating composite product. It is utilized in aerospace engineering, or the boron nitride powder can be directly covered on the guide rail surface. The boron nitride suspension oil is white or yellow. Therefore, it does not pollute fibre items in textile machinery as well as can be extensively made use of in the lubrication of artificial fibre textile machinery.

Is Boron nitride hazardous to human body?
Boron nitride is not harmful, yet boron nitride powder is a cloud of dust unsafe to human health and wellness. Boron nitride powder is literally inert and also will certainly be detrimental to wellness when swallowed, inhaled, and also exposured to the skin and also eyes. Consuming or inhaling will trigger skin, breathing system, and also kidney blood circulation disorders.

Cost of boron nitride
Boron nitride particle size as well as purity will influence the item'' s price, and the acquisition quantity can likewise affect the expense of boron nitride. A huge amount of big quantity will certainly be reduced. The price of boron nitride can be found on our business'' s official internet site.
