From 2-D to 0-D Boron Nitride Materials, The Next Challenge
Among other materials, boron nitride (BN) nanomaterials have shown remarkable features with the possibility of being used in a large variety of devices. Photonics, aerospace, and medicine are just some of the possible fields where BN has been successfully employed. Poor scalability represents, however, a primary limit of boron nitride.Hexagonal boron nitride (h-BN) is a nontoxic, lightweight ceramic material which is stable up to ~800–1000 °C in air [1–3] and 2700–3000 °C in inert atmospheres [4, 5].Like graphite, h-BN possesses a layered atomic structure and is known for its high basal-plane thermal conductivity, with representative values of 350 W m −1 K −1 at 300 K [] Three-dimensional foam-like hexagonal boron nitride

Pre-Ball-Milled Boron Nitride for the Preparation of Boron Nitride
Modern electronics not only require the thermal management ability of polymer packaging materials but also need anti-voltage and mechanical properties. Boron nitride nanosheets (BNNS), an ideal thermally conductive and high withstand voltage (800 kV/mm) filler, can meet application needs, but the complex and low-yield process limits BNs have recently been identified in natural minerals and a variety of various forms, including graphite-like helical boron nitride (g-BN or h-BN), cubic boron nitride (c-BN), wurtzite boron nitride (w-BN), and amorphous boron nitride (a-BN). Among them, h-BN is the most commonly used crystal structure of BNs [65]. As a result, severalFabrication, characteristics, and applications of boron nitride
