Aluminum powders were electrodeposited on a tungsten cathode in an electrolytic bath including aluminum trichloride of a major component, separated from the bath by filtering under reduced pressure in the hot molten state, and the bath was cooled. The remained bath was dissolved in agitating ice water. Aluminum powders were recovered by filtering with a cotton cloth and dried at 250°C in an electric furnace. With rising bath temperature or lowering current density, powders are coarsened and their alumina contents are reduced. To produce powders of low alumina content under 2%, aluminum should be electrodeposited at low current density. Aluminum powders with a wide range of desired particle size distribution and aimed alumina content between 1.4% and 30% are produced by this process at the optimum. bath temperature and current density.
