  • Method of making metallic powders by aerosol thermolysis
    Patent number: 5928405
    Abstract: An economical process and associated hardware for commercial manufacture of controllable submicrometer size metallic powders for electronic and other applications. The method is based on the preparation of a stable high concentration precursor solution, production of a high density aerosol mist of the precursor solutions, selection of mist droplets with upper and lower size bounds, controlled drying of the droplets, their conversion to metallic powder in a high temperature gaseous atmosphere and the separation of the powders from carrier gases without significant loss inside the process hardware.
