Abstract: The present invention provides a process for the electroless plating of easily reducible metals onto ultrafine, usually inert, particles. Such plating is achieved through careful and accurate control of such parameters as the feed rates of the various solutions, the control of pH of the solution, the temperature, pressure and the rate of agitation of the solution in which the plating is taking place. The plated ultrafine composite particles and the powders made from the particles produced by the process are also a part of the invention. There is also provided a metal article of manufacture consisting of a metal such as copper, silver, gold, ruthenium, rhodium, palladium, osmium and platinum with a plurality of spherical shaped ultrafine particles with a diameter of less than about 10 microns dispersed substantially evenly through the metal article.

Abstract: Refractory metal oxide particles are dispersed in an aluminum melt which is then cast to form a dispersion hardened aluminum alloy composition. A master mix of carrier metal particles surrounding individual oxide particles is pressed into a billet. The billet is dissolved in the melt in the presence of a wetting metal.
