  • Method of producing high-purity ultra-fine metal powder
    Patent number: 5476535
    Abstract: A method of producing a high-purity, ultra-fine powder of a first metal, particularly silver, by forming an alloy of the first metal with a second metal, such as aluminum subjecting the alloy to a leaching agent effective to leach out the second metal, leaving a porous first metal agglomerate; mixing the porous first metal agglomerate with a fresh batch of leaching agent; disintegrating the agglomerate and applying ultrasonic oscillations to the mixture to enhance the penetration of the leaching agent into the pores of the agglomerate; removing the leaching agent, leaving the first metal; and washing and drying the first metal.
