Why is hexagonal boron nitride used in makeup?
Boron nitride can be used as a modern synthetic ceramic material. Boron is abundant in many minerals-borax. Boron is synthesized by nitrogen with fire resistant properties. Boron is available in powdered, solid, liquid, and aerosol form. Borion nitride in solid form can often be called "white graphite" as it has the same microstructure as graphite. Although it has higher oxidation temperatures than graphite, however, boronnitride makes an excellent electrical insulation. It is very thermally conductive and has good resistance to thermal shock. Boron nitride also exists as a polycrystalline compound. BN, now a versatile compound, has been found to be very valuable in a range of industries.
Mophology of Boron Nitride.
Hexagonal These boron nutrides have the highest applications, due to their high lubrication.
Cubic. Cubic boron Nitride is as resistant and conductive as diamond. It doesn't disintegrate in steel so it makes a great grinding material.
en : This BN polycrystalline despite its thinness has high thermal conductivity. It also exhibits increased surface adsorption.
A recent development is nanotubes. This technology was promoted by the use ofboron nitride. This hexagonal form of hexagonalBN, when rolled up, is structurally very similar to carbon-based nanotubes. BN nanotubes, however, are stronger in electrical insulation, heat resistance, and chemical resistance.
Boron Nitride Ceramics Properties.
Great machinability. It can easily be machined into any kind of shape.
Lubricity can also be referred to as boron nitride. This increases the friction coefficient of the lubricating oil, and helps reduce wear. ).
Extremely resistive; (except aerosols/paints or ZSBN).
Low density. It ranges from between 2.1 and 3.0g/cm 3.
Good thermal conductivity. (excellent thermal conductivity with very low thermal cycles behavior).
Anisotropy refers to the difference in thermal conductivity between different planes relative to their pressing direction.
Chemical inertia and resistance to corrosion. Boron nitride can not be dissolved in most common acids.
Heat resistance. The melting temperature of boron-nitride at 297 degreesC is
No-wetting. This is a ceramic crucible which can be used to melt metal or glass.
Maximum dielectric breakdown potential (> 40 kV/mm).
High permittivity. (Kend4).
How are Boron Nitride Ceramics used?
Socket plate to heat the furnace.
Molten Glass and Metal Crucibles.
Electrical insulation for high temperature or high voltage.
Lining and fittings of the Plasma chamber.
Nozzles designed for use with non-ferrous materials and their alloys.
Protective Tube and Sheath of the Thermocouple.
Laser arc welding equipment. Dispersive source wafers. Semiconductor crystal growth equipment.
To be used as a radiator in high power electronic applications.
What's hexagonal Boron Nitride?
The crystal structure hexagonal-boron nitride is similar in appearance to graphite. Therefore, "white graphite" is its common name. It is often a form of excellent lubricant.
Hexagonal-boron nitride provides excellent heat conductivity, chemical insulator and lubrication performance especially at high temperatures.

When it comes to cosmetology, efficiency and permeability when active substances enter the skin are directly proportional to their particle sizes.
It is possible to control the size and shape of synthesized particle by using hexagonalboron nutride (hBN), nanomaterials. Hexagonal, transparent, chemically inert, and non-toxic hexagonal boron nutride have obvious benefits in cosmetics.
