ORGANOBORON ROUTE AND PROCESS FOR PREPARATION OF BORON NITRIDE

摘要

An organoboron route and process for preparation of boron nitride utilizing aerosol assited 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 sphroidal boron nitride powders including spheroidal particles that are smooth, bladed, have protruding whiskers, and are of turbostratic or hexagonal crystalline structure. The aerosol assisted vapor phase reactor system (AAVS) 10 comprises aerosol generator assembly 12, inert carrier gas source 14, nitriding source 16, connection systems 18, 18,'18," furnance 20, preferably, collection device 41.
