Filed:

May 19, 1999

Appl. No.:

09/315097

Inventors:

Robert T. Paine - Albuquerque NM
William J. Kroenke - Albuquerque NM
Eugene A. Pruss - Albuquerque NM

Assignee:

University of New Mexico - Albuquerque NM

International Classification:

C01B 21064

US Classification:

423277, 432290

Abstract:

The present invention involves a process and system for producing spherical BN O particles that are converted to crystalline BN. The process involves adding a boron compound to an aqueous solution, creating an aerosol spray from the solution in the form of aerosol droplets using an aerosol generator. The aerosol droplets are fed with an inert carrier gas into a heated furnace at a preset flow rate while simultaneously injecting a gaseous nitriding agent into the heated furnace in a direct proportion to the flow rate of the carrier gas containing the aerosol droplets whereby a precursor of spherically shaped BN O particles are formed which are further heat treated into particles of spherically shaped BN having a turbostratic or hexagonal structure.

International Classification:

C01B 3510

US Classification:

423277, 423290

Abstract:

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.

US Classification:

423290, 23293 R, 219764, 428402, 428901

Abstract:

Novel boron nitride agglomerated powders are provided having controlled density and fracture strength features. In addition methods for producing same are provided. One method calls for providing a feedstock powder including boron nitride agglomerates, and heat treating the feedstock powder to form a heat treated boron nitride agglomerated powder. In one embodiment the feedstock powder has a controlled crystal size. In another, the feedstock powder is derived from a bulk source.
