ABSTRACT:
Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator (106) including a plurality of ultrasonic transducers (120) underlying and ultrasonically energizing a reservoir of liquid feed (102) which forms droplets of the aerosol. Carrier gas (104) is delivered to different portions of the reservoir by a plurality of gas delivery ports (136) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders made by the method and devices made using the powders.
