What is boron nitride?
Boron nitride is a synthetic boron-based inorganic compound used in cosmetics and personal care products to increase adherence and act as an oil absorbent. Boron compounds are also used in skin care products to kill bacteria and remove dead skin cells and excess oil. While it is considered safe for use on the skin, it is important to use it in small quantities to avoid any potential irritation. In its cubic form (c-BN), it shares the same crystalline structure as diamond, but instead of carbon atoms is made up of alternately-bonded atoms of boron and nitrogen. Boron nitride is tricky to substitute. Sericite mica has similar properties but does not improve adhesion nearly as well as boron nitride, so you might consider using a blend of sericite mica and an adhesion booster like magnesium stearate or magnesium myristate as a starting point.
What is boron nitride used for?
Different applications are possible by exploiting these properties. BN nanostructures are used for thermal conductivity enhancement, mechanical strength enhancement, insulating coatings, oxidation and corrosion-resistant coatings, electrical circuits, water treatment, and hydrogen storage. In Skin Care, Boron Nitride offers high oil absorption capacity, regulating moisture and protecting skin from drying out. A high degree of thermal conductivity creates the sensation of a cooling effect. The material sold in solid form is generally not considered hazardous. However, if the process involves grinding, melting, cutting, or any other process that causes a release of dust or fumes, hazardous levels of airborne particulates could be generated.
How strong is boron nitride?
Boron nitride (B4N) is a crystalline material synthesized from boric anhydride and pure low-ash carbon material in electric furnaces at 1,800°C− 2,500°C (3,300°F–4,500°F). Its hardness is about 3,800 HV, and it has a good cutting ability in the form of loose grains. (PhysOrg.com) — Currently, diamond is regarded as the world's hardest-known material. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond. Boron nitride can be compressed into a superhard, transparent form—but unlike diamond and many other materials known for their extreme hardness, it is based not on carbon but on a latticework of boron and nitrogen atoms. In general, that's true: The two materials have similar values for strength and elasticity, but h-BNs are slightly lower. Graphene has a strength of about 130 gigapascals for strength and 1.0 terapascals for elasticity; h-BN's values are 100 gigapascals and 0.8 terapascals, respectively. Boron nitride reacts with iodine fluoride in trichlorofluoromethane at −30 °C to produce an extremely sensitive contact explosive, NI 3, in low yield.
