How heat resistant is boron nitride

What is boron nitride?
Boron nitride is typically black, brown or dark red crystals with sphalerite structure and also great thermal conductivity. Its firmness is second just to diamond, a superhard product frequently used as device materials as well as abrasives. Boron nitride has chemical resistance as well as no erosion by inorganic acid as well as water. The boron nitrogen bond is broken in warm, concentrated antacids. Oxidation starts in the air at 1200 ℃. Decay starts at regarding 2700 ℃ in a vacuum cleaner. It is slightly soluble in hot acid and insoluble in cool water. The relative density is 2.29. The compressive toughness is 170 mph. The maximum service temperature is 900 ℃ in the oxidation environment as well as 2800 ℃ in the non-active decrease environment, however the lubrication performance is bad at space temperature level. Many properties of boron nitride are much better than carbon products. For hexagonal boron nitride: the friction coefficient is superficial Excellent high-temperature stability, excellent thermal shock resistance, high toughness, high thermal conductivity, reduced growth coefficient, high resistivity, rust resistance, microwave or infrared transmission.


What is the role of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, advanced refractories as well as superhard material; splitting up rings for continual straight rolling, high-temperature resistant lubricants and high-temperature finishings. It is additionally a resources for synthesizing cubic boron nitride. In addition, it is additionally an extremely exceptional high-temperature lube, which can be made use of as a component of self-lubricating bearings. Boron nitride has several physical buildings similar to graphite, called white graphite. It is similar to mica, talcum powder, and silicate; Fats are collectively described as white strong lubes. As a lubricating substance, boron nitride can be dispersed in heat-resistant lubricating grease, water or solvent; It is splashed on the rubbing surface area to develop a completely dry movie after the solvent volatilizes and then completed the material, ceramic, and also steel surface area layers as a high-temperature resistant self-lubricating composite material. It is used in aerospace engineering, or the boron nitride powder can be directly coated on the overview rail surface area. The boron nitride suspension oil is white or yellow. As a result, it does not pollute fiber items in fabric equipment as well as can be extensively made use of in the lubrication of synthetic fibre textile machinery.

Is Boron nitride unsafe to human body?
Boron nitride is not toxic, yet boron nitride powder is a cloud of dirt damaging to human wellness. Boron nitride powder is literally inert and also will certainly be damaging to wellness when swallowed, inhaled, and exposured to the skin and also eyes. Consuming or breathing in will certainly create skin, breathing system, and kidney blood circulation disorders.

Price of boron nitride
Boron nitride fragment dimension and also purity will impact the item'' s price, as well as the acquisition quantity can also affect the cost of boron nitride. A big amount of big quantity will be lower. The price of boron nitride can be found on our business'' s official site.
