Boron Nitride Insulator, BN Ceramic Insulators

In addition to high thermal conductivity, hexagonal boron nitride also has excellent insulation properties. Its band gap width is 5.2eV and its breakdown strength is as high as 35kV/mm, which makes h-BN suitable for working conditions that require both insulation and heat dissipation, which is unmatched by graphene. It is precisely because of the above excellent properties that hexagonal boron nitride is a thermally conductive filler with great application value and prospects. Edgetech Industries LLC provides processing services for boron nitride insulators.

Application of Boron Nitride Insulator

With the development of science and technology, the requirements for miniaturization and integration of electronic products are getting higher and higher. Heat dissipation problems affect the working efficiency and service life of products, thus restricting the development of microelectronic integration technology. In recent years, researchers have further improved the thermal conductivity of hBN hexagonal boron nitride-based thermal conductive composite materials through blending, surface modification, hybridization effect, 3D structure construction, and other methods, so that they can be better used in electronic components.
