Abstract

Synthesis and research of the properties of boron nitride powders and BN powders with additives produced under effect of concentrated light in a flow of nitrogen in a xenon high-flux optical furnace are presented. A scanning and transmission electron microscopes demonstrated structures of new morphologies for the powders, which were formed. XRD, Raman scattering and electron diffraction study have confirmed a complicated structure and phase composition of the powders with a prevalence of the amorphous phases. It was demonstrated an effect of experimental conditions, surface modification and additives on phase composition, morphology and structure formation. The gaseous model based on an evolution of the bubble has been confirmed new nanostructure formation. Burst of these bubbles may result in graphene-like structures formation.
