How heat resistant is boron nitride
What is boron nitride?
Boron nitride is typically black, brownish or dark red crystals with sphalerite structure and also great thermal conductivity. Its firmness is second only to ruby, a superhard material commonly utilized as device products and abrasives. Boron nitride has chemical resistance as well as no disintegration by inorganic acid and water. The boron nitrogen bond is broken in warm, focused alkali. Oxidation begins in the air at 1200 ℃. Disintegration starts at about 2700 ℃ in a vacuum. It is slightly soluble in warm acid and also insoluble in chilly water. The relative thickness is 2.29. The compressive stamina is 170 mph. The maximum service temperature level is 900 ℃ in the oxidation environment and 2800 ℃ in the non-active reduction atmosphere, but the lubrication performance is inadequate at room temperature. A lot of residential properties of boron nitride are far better than carbon products. For hexagonal boron nitride: the rubbing coefficient is superficial Good high-temperature stability, great thermal shock resistance, high stamina, high thermal conductivity, reduced development 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, progressed refractories and superhard product; separation rings for continuous straight rolling, high-temperature immune lubes and also high-temperature finishings. It is also a basic material for synthesizing cubic boron nitride. On top of that, it is also an extremely outstanding high-temperature lube, which can be used as an element of self-lubricating bearings. Boron nitride has numerous physical residential properties similar to graphite, called white graphite. It is similar to mica, baby powder, and also silicate; Fats are collectively described as white strong lubricating substances. As a lube, boron nitride can be dispersed in heat-resistant lubricating oil, water or solvent; It is sprayed on the rubbing surface area to create a dry film after the solvent volatilizes and after that filled in the material, ceramic, as well as metal surface layers as a high-temperature immune self-lubricating composite material. It is utilized in aerospace design, or the boron nitride powder can be straight covered on the overview rail surface. The boron nitride suspension oil is white or yellow. As a result, it does not contaminate fiber products in textile equipment and also can be extensively utilized in the lubrication of artificial fiber textile equipment.
Is Boron nitride harmful to body?
Boron nitride is not harmful, however boron nitride powder is a cloud of dust damaging to human health. Boron nitride powder is literally inert and also will certainly be damaging to health and wellness when swallowed, inhaled, as well as exposured to the skin and eyes. Consuming or breathing in will cause skin, breathing system, and kidney circulation conditions.
Rate of boron nitride
Boron nitride fragment size and also purity will certainly influence the item'' s cost, and also the purchase quantity can likewise influence the expense of boron nitride. A big amount of huge amount will certainly be reduced. The cost of boron nitride can be found on our firm'' s official site.
