Abstract:
1. A method of forming boron nitride nanoparticles, comprising the steps of: a) volatilizing a plurality of first precursor molecules comprising boron, nitrogen and hydrogen in a first heating zone having a first predetermined temperature to form a plurality of gaseous second precursor molecules that comprise bonded substantially unoxidized boron and nitrogen; b) directly carrying the gaseous second precursor molecules comprising bonded substantially unoxidized boron and nitrogen entrained in a gas flow to a second heating zone having a second predetermined temperature thereby causing the molecules to react and nucleate to form a plurality of solid boron nitride nanoparticles while entrained in the gas flow, comprising substantially unoxidized boron and nitrogen; and c) collecting the boron nitride nanoparticles.
