Patent number: 6699304Abstract: Provided are palladium-containing powders and a method and apparatus for manufacturing the palladium-containing particles of high quality, of a small size and narrow size distribution. An aerosol is generated from liquid feed and sent to a furnace, where liquid in droplets in the aerosol is vaporized to permit formation of the desired particles, which are then collected in a particle collector. The aerosol generation involves preparation of a high quality aerosol, with a narrow droplet size distribution, with close control over droplet size and with a high droplet loading suitable for commercial applications. Powders may have high resistance to oxidation of palladium. Multi-phase particles are provided including a palladium-containing metallic phase and a second phase that is dielectric. Electronic components are provided manufacturable using the powders.Type: GrantFiled: September 22, 2000Date of Patent: March 2, 2004Assignee: Superior Micropowders, LLCInventors: Mark J.

Patent number: 6685762Abstract: A process for making particles, the process including generating an aerosol stream which includes droplets of a precursor liquid dispersed in a carrier gas, the precursor liquid including a liquid vehicle and a precursor material, separating the precursor liquid into two portions during the generating step, a first portion exiting the generator in the droplets of the aerosol stream and a second portion exiting as effluent at least a portion of which is recycled to the generator, and also during the generating step adding additional liquid vehicle to at least one of the carrier gas supply, the precursor liquid supply, and the aerosol generator, to at least partially compensate for the tendency of the precursor liquid to become more concentrated in the precursor material over time, and then removing at least a portion of the liquid vehicle from the droplets and forming particles in the aerosol stream.Type: GrantFiled: February 11, 2002Date of Patent: February 3, 2004Assignee: Superior MicroPowders LLCInventors: James H.

Patent number: 6635348Abstract: 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.
