What is Boron Nitride?
Boron Nitride (BN) is a synthetic compound of boron and nitrogen, which exists in several crystalline forms. Among these, hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN) are the most widely studied. Boron nitride exhibits remarkable properties such as high thermal conductivity, excellent chemical stability, and electrical insulation.
Why is Boron Nitride Important in Nanotechnology?
In the realm of
Nanotechnology, boron nitride has gained significant attention due to its unique properties. For instance, h-BN, often referred to as "white graphene," has a similar layered structure to
graphene but with an insulating nature. This combination makes it an excellent candidate for various applications, including thermal management in nanoelectronics, protective coatings, and
nano-composites.
