Structure, Properties, and Applications of Graphite-Like Hexagonal Boron Nitride.

A review of the literature is presented, including a description of the crystal structure and morphological features of graphite-like hexagonal boron nitride, as well as the preparation of materials based on it. The mechanical and dielectric properties of pyrolytic, hot-pressed (hexagonal and turbostratic modification) and reactive sintered boron nitride are presented. The positive effect of impregnation of porous samples based on boron nitride with organoboron and organosilicon compounds, followed by pyrolysis, on the level of physicomechanical characteristics is shown.
