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 including a plurality of ultrasonic transducers underlying and ultrasonically energizing a reservoir of liquid feed which forms droplets of the aerosol. Carrier gas is delivered to different portions of the reservoir by a plurality of gas delivery ports 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.

1. A method, comprising: depositing a composition comprising a glass frit onto a substrate, the composition comprising metallic particles having a weight average particle size lower than 2 microns, wherein the metallic particles comprise multi-phase particles comprising a first phase and a second phase; andheating the deposited composition to form an electrically conductive feature. 2. The method of claim 1 wherein the second phase is in the form of a coating around a core of the first phase. 3. The method of claim 1 wherein the first phase is a metallic phase. 4. The method of claim 3 wherein the second phase is a metallic phase different from the first phase. 5. The method of claim 1 wherein the second phase comprises the glass frit. 6. The method of claim 1 wherein the second phase comprises an oxide. 7. The method of claim 6, wherein the oxide comprises an oxide of zinc, tin, barium, molybdenum, manganese, vanadium, niobium, tantalum, tungsten, iron, silver, chromium, cobalt, nickel, copper, yttrium, iridium, beryllium, silicon, zirconium, aluminum, bismuth, magnesium, thorium or gadolinium. 8. The method of claim 6 wherein the oxide comprises silica, alumina, titania, zirconia or yttria, or an oxide of copper, bismuth or tin. 9. The method of claim 1 wherein at least 90 weight percent of the metallic particles are smaller than twice the weight average size of the particles. 10. The method of claim 1 wherein the second material phase comprises less than 30 weight percent of the particles. 11. The method of claim 1 wherein the metallic particles are not jagged in shape. 12. The method of claim 1 wherein the metallic particles comprise metal nanoparticles. 13. The method of claim 1 wherein the metallic particles comprise an alloy. 14. A method, comprising: depositing a composition onto a substrate, the composition comprising metallic particles having a weight average particle size lower than 2 microns, wherein the metallic particles are formed through an aerosol method and comprise multi-phase particles comprising a first phase and a second phase; andheating the deposited composition to form an electrically conductive feature. 15. The method of claim 14 wherein the second phase is in the form of a coating around a core of the first phase. 16. The method of claim 14 wherein the first phase is a metallic phase. 17. The method of claim 14 wherein the second phase comprises an oxide. 18. The method of claim 14, wherein the oxide comprises an oxide of zinc, tin, barium, molybdenum, manganese, vanadium, niobium, tantalum, tungsten, iron, silver, chromium, cobalt, nickel, copper, yttrium, iridium, beryllium, silicon, zirconium, aluminum, bismuth, magnesium, thorium or gadolinium. 19. The method of claim 14 wherein at least 90 weight percent of the metallic particles are smaller than twice the weight average size of the particles. 20. The method of claim 14 wherein the metallic particles comprise metal nanoparticles.
