Abstract:
1. A method of forming a boron-nitrogen-oxygen-carbon-hydrogen, BN x O y C z , precursor for BN comprising: providing a boron precursor, an inert carrier gas, and a nitriding agent, wherein said precursor is dissolved in solution, having a solvent selected from the group consisting of non-aqueous solvent and partially aquated solvent, thereby forming a boron precursor solution, wherein partially aquated boron precursor solutions contain less than or equal to 50 wt. % water; aerosolizing the boron precursor solution; forming a combined gas stream by introducing the carrier gas into a chamber containing the aerosolized precursor; heating the combined gas stream in a heated furnace; introducing the nitriding agent into the furnace; and reacting the nitriding agent and aerosolized precursor solution to react to form a powder of a boron-nitrogen-oxygen-carbon composition.
