A method for producing a metal powder includes maintaining molten reducing metal in a sealed reaction vessel that is substantially free of oxygen and water, establishing a vortex in the molten reducing metal, introducing a metal halide into the vortex so that the molten reducing metal is in a stoichiometric excess to the metal halide, thereby producing metal particles and salt, removing unreacted reducing metal, removing the salt, and recovering the metal powder. The molten reducing metal can be a Group I metal, a Group II metal, or aluminum.
