What is Hexagonal Boron Nitride?

Boron nitride is a crystal composed of nitrogen atoms as well as boron atoms. The crystal framework is separated right into: hexagonal boron nitride (HBN), close-packed hexagonal boron nitride (WBN) in addition to cubic boron nitride, among which hexagonal boron nitride crystals The framework has a similar graphite split structure, showing a white powder that is loose, oiled, extremely easy to take in dampness, as well as likewise light in weight, so it is also called “white graphite”.
The development coefficient of hexagonal boron nitride is equivalent to that of quartz, however the thermal conductivity is 10 times that of quartz. It also has great lubricity at heat. It is a fantastic high-temperature strong lubricating substance with strong neutron absorption capability, steady chemical residences, as well as also chemical inertness to almost all liquified metals.
Hexagonal boron nitride is insoluble in cold water. When the water is steamed, it hydrolyzes incredibly slowly and likewise generates a small amount of boric acid and likewise ammonia. It does not react with weak acids and also strong bases at space temperature level. It is a little soluble in warm acids. Use molten sodium hydroxide, potassium hydroxide handling to degeneration. It has significant anti-corrosion capability to various not natural acids, antacid, salt solutions and likewise natural solvents.
Cubic boron nitride is a superhard item whose firmness is second only to ruby. It was first created by R.H. Wentorf of the USA in 1957. It not simply has a number of exceptional buildings of ruby, yet additionally has greater thermal protection and resistance to iron. Chemical protection of group metals. It is commonly used to improve ferrous steels such as hard steel, chilled actors iron and also heat-resistant alloys.It does not respond with weak acids as well as solid bases at area temperature level. It is a little soluble in warm acids. Usage molten salt hydroxide, potassium hydroxide handling to decay. It has considerable anti-corrosion capability to different not natural acids, antacid, salt remedies and also organic solvents.
Cubic boron nitride is a superhard product whose suppleness is 2nd only to ruby. It was first created by R.H. Wentorf of the United States in 1957. It not just has a number of exceptional buildings of diamond, yet furthermore has greater thermal safety as well as resistance to iron. Chemical safety of team metals. It is commonly made use of to fine-tune ferrous steels such as difficult steel, chilled actors iron and also heat-resistant alloys.

Hexagonal Boron Nitride Uses

  1. Hexagonal Boron Nitride is used to make refractory materials, heater insulation products, and additionally made use of in electronics, equipment, aeronautics as well as other industries.
  2. Hexagonal Boron Nitride has a variety of outstanding buildings and also is widely used in insulators for high-voltage high-frequency electric and also plasma arcs, layers for automatic welding high-temperature immune frames, products for high-frequency induction heaters, solid-phase admixtures for semiconductors, and also atomic reactor structures. Formed boron nitride can be utilized to make high temperature crucibles as well as various other products. It can be used as superhard material, suitable for drill little bits and also high-speed cutting devices for geological expedition as well as oil exploration. It can also be used as an unpleasant material for steel handling, and also has the characteristics of low handling surface area temperature and also less surface area problems of parts.
  3. Hexagonal Boron Nitride is used as mold release agent for metal creating and lubricant for steel cable illustration; special electrolysis and resistance materials at high temperature; strong lube; warmth securing desiccant for transistors and also additives for polymers such as plastic materials; pressed into numerous Hexagonal Boron Nitride items in various shapes can be utilized as high temperature, high pressure, insulation and also heat dissipation parts; heat shielding materials in the aerospace sector; with the involvement of stimulants, it can be exchanged cubic boron nitride as difficult as diamond after heat and also high pressure therapy.

Hexagonal Boron Nitride Production Method

The boron trichloride ammonia vapor deposition method fully mixes the prepared boron trichloride and hydrogen with ammonia gas heated to a certain temperature, reacts in the reactor at the specified reaction temperature, and then reacts at a higher temperature. At the same temperature, continue to heat for a certain period of time in the flow of ammonia to obtain the finished product of Hexagonal Boron Nitride. Its BCl3+2NH3→BN+2HCl+NH4Cl

Borax ammonium chloride method Dehydrates borax at 450°C and pressure of 79993Pa, ammonium chloride is pre-dried at 110-120°C, and pulverized to a fineness of 40 meshes respectively. According to the mass ratio of anhydrous borax and ammonium chloride of 1:0.59, the ingredients are mixed and pressed into shape. Then, it is sent to the reaction furnace, and excess ammonia is introduced, and the reaction is carried out at 1050 ° C to generate Hexagonal Boron Nitride coarse crystals. After crushing, sieving, washing, filtration and drying, the finished Hexagonal Boron Nitride is obtained. Its Na2B4O7+2NH4Cl+2NH3→4BN+2NaCl+7H2O

The manufacture of cubic crystal Hexagonal Boron Nitride can be prepared by using hexagonal crystal as raw material, adding magnesium powder, and adding lithium hydride powder as an additive under high pressure and high temperature.

The Production Process and Characteristics of Hexagonal Boron Nitride

Hexagonal Boron Nitride is readily available in four different versions: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) as well as wurtzite boron nitride (WBN).

Hexagonal Boron Nitride eutectes B2O3 with NH4Cl, or burns important boron in NH3 to produce BN. The boron nitride typically acquired is a graphite-type structure, generally called white graphite. The various other is diamond kind. Similar to the concept of transforming graphite right into ruby, graphite-type boron nitride can be exchanged diamond-type boron nitride at heat (1800 ° C )and also high pressure (800Mpa). The B-N bond size (156pm) in this boron nitride resembles the C-C bond size (154pm) of diamond, as well as its density resembles that of ruby. Its hardness is comparable to that of diamond, as well as its warm resistance is far better than that of diamond. It is a new sort of heat immune superhard material for making drills, abrasives and also cutting devices.

Hexagonal Boron Nitride is corrosion-resistant, has great electrical insulation, as well as has a specific resistance above 10-6 Ω. centimeters; compressive strength is 170MPa; thermal growth coefficient in the c-axis instructions is 41 × 10-6/ ° C and also -2.3 × 10-6 in the d-axis instructions; the maximum operating temperature level in an oxidizing environment is 900 ° C, It can get to 2800 ° C in an inactive reducing atmosphere, however the lubricating efficiency is poor at room temperature level, so it is typically blended with fluorinated graphite, graphite as well as molybdenum disulfide as a high-temperature lubricating substance, and also the boron nitride powder is dispersed in oil or water. It can be utilized as a lube for cord drawing or press forming, and also as a lubricant for moving components in heat furnaces. The sintered body of Hexagonal Boron Nitride can be made use of as a material for bearings as well as gliding get rid of self-lubricating buildings.
