TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The production of metal particles further includes containing a dissolved metal solution of a molarity to prevent the formation of dendrites on the active zones, and maintaining an electric current from the anode to the cathode sufficient to prevent the formation of dendrites on the active zones.Preferred Component: The dissolved metal is in a form of oxide(s) of the metal. The solution is a reaction product of an electrochemical reaction in a metal/air fuel cell. The dissolved metal is zinc. The solution is an aqueous solution. The aqueous solution comprises dissolved electrolyte and a suspension of metal oxide. The solution is a non-aqueous solution.Preferred Property: The molarity of the dissolved metal is between 0.1-4.5M. The current is between 0-300 amps. The solution flow has a Reynolds number greater than 1500. The dissolved electrolyte has an initial concentration between 25-55 wt.%.Preferred Process: The production of metal particles further includes forming metal particles of a size that generally relates to the size of the active zones, collecting the metal particles from the active zones when the particles achieve a desired size, relatively moving the active zones and a scraping device so that the particles are dislodged and directed to a collection area, relatively moving the active zones and the insulator so that the particles are dislodged and directed to a collection area, dislodging the particles by vibrating the cathode, mechanically shocking the cathode, or increasing the flow of the solution, and directing the dislodged particles to the collection area through flow of the solution or gravity. The current density in the active zones is maintained between 10-40 kA/m2. The temperature is maintained between 20-80, preferably 40-55degreesC.
