  • Palladium-containing particles, method and apparatus of manufacture, palladium-containing devices made therefrom
    Patent number: 7172663
    Abstract: 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.
