Hexagonal boron nitride is being used widely across different industries all over the globe for the numerous benefits that it can provide.

When people all over the world thought about making 2D materials, hexagonal boron nitride became quite famous because of its optoelectrical property. When all the properties got mixed properly with mechanical robustness, chemical inertness and thermal stability, the mixture can make a sturdy 2D material. In the science community, all around the globe, h-BN layers that are very superthin in nature gets quite special attention. The usage of the superthin layers in nanoelectronics, photonics, biomedical, catalysis and many more cannot go undervalued.

The usage of hexagonal boron nitride in the 2D industry become quite famous because of the thermal, structural, optical and mechanical properties that it has. It is used in various ways like as a chemical exfoliant, physical vapour depositor and many other combinations to make things a lot easier.

The Actual Properties Of Boron Nitride

Thermal Conductivity: The ...
... thermal conductivity of boron nitride ranges from 1700 up to a whopping 2000 W/mK and it is quite comparable to graphene. The compound also consists of a hexagonal lattice which is created by carbon atoms.

Heat And Chemical Resistance: The thermal enlargement coefficient of boron nitride is much than that of a diamond also and 2,973°C is its melting point.

Density: The density of hexagonal boron nitride depending on the form ranges from 2.1 up to up to 3.5 grams per cubic centimetre.

Lubrication: Used enormously for oil lubrication, boron nitride also helps in increasing frictional coefficient and also with that reduces wear and tear as well.

Production Process Of Boron Nitride

The synthesis reaction that is the result of boric acid or boron trioxide gives rise to boron nitride. This is what is referred to as the boron precursor containing either urea or ammonia (a nitrogen reagent). This reaction helps the boron oxide to achieve an amorphous shape and thus also have enough amount of impurities of boron trioxide. After this process, it is quite possible to get rid of these impurities by a simple process of evaporation and for that, it should be heated over a temperature of 1500°C.

All these aspects make boron nitride an interesting compound because of its numerous forms and polymorphs that really exist in the real world.

All these are some detail of hexagonal boron nitride. It is quite a versatile material and for its versatility, it has vast use in different types of industries all over the globe.
