Applications of hexagonal boron nitride (hBN)
hBN, or hexagonal boron nitride, is sometimes referred to as "white graphite" due to its similarities with graphite in terms of properties, except for electric conductivity. hBN has low wetability with molten metal and is a strong electric insulator. Not only can hBN be used in powder form, but it can also be sintered to form a machinable ceramic material. Here are some of the applications of hBN:
1.Release agent: hBN can be used as a release agent for metal forming and a lubricant for metal drawing.
2.Special materials: hBN is used for special electrolytic and resistance materials at high temperatures.
3.Solid lubricants: hBN is suitable for high-temperature solid lubricants, extrusion anti-wear additives, additives for ceramic composite materials, refractories, and anti-oxidation additives, especially for anti-molten metal Faust occasions, heat-strengthening additives, and high-temperature-resistant insulating materials.
4.Polymer additives: hBN is suitable for heat sealing desiccant of transistor and additive of polymer such as plastic resin.
5.Components: hBN products pressed into various shapes can be used as high-temperature, high-voltage, insulation, and heat dissipation components.
6.Heat shielding: hBN is used as a heat shielding material in aerospace.
7.Superhard material: hBN can be transformed into cubic boron nitride, as hard as diamond, after high-temperature and high-pressure treatment in the presence of a catalyst.
8.Atomic reactor: hBN is the structural material of the atomic reactor.
9.Aerospace: hBN is suitable for the nozzle of aircraft and rocket engines.
10.Insulator: hBN is used as the insulator of high voltage, high frequency, and plasma arc.
11.Packaging: hBN is a packaging material to prevent neutron radiation and is used for all kinds of fresh-keeping aluminized packaging bags.
12.Metallurgy: hBN is used in metallurgy for separating ring of continuous casting steel, the notch of amorphous iron, and the crucibles for melting metals in a lot of cases.
13.Evaporating boat: hBN is used as a kind of evaporating boat for aluminizing capacitor film, picture tube, and display.
14.Cosmetics: hBN is the best lipstick in France, suitable for cosmetics and used as a lipstick filler. It has lubricity and luster.
In summary, hBN has a wide range of applications in various fields, including metallurgy, aerospace, and cosmetics. Its unique properties make it a versatile material that can be used in many different ways.
