Organoboron route and process for preparation of boron nitride

摘要

An organoboron route and process for preparation of boron nitride utilizing aerosol assisted vapor phase synthesis (AAVS) wherein organoboron precursors are nitrided in one or two heating steps, and wherein a boron oxide nitride intermediary composition is formed after the first heating step and may be further nitrided to form resultant spheroidal boron nitride powders including spheroidal particles that are smooth, bladed, have protruding whiskers, and are of turbostratic or hexagonal crystalline structure.
