Abstract
A method for producing a metal powder includes maintaining molten reducing metal in a sealed reaction vessel that is free of added 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.

Abstract
A method for producing a metal powder that combines molten reducing metal and metal halide in a space that is substantially free of oxygen and water, wherein the molten reducing metal is sodium and/or potassium, or aluminum (or magnesium or titanium) and is present in a stoichiometric excess to the metal halide which is a solid or liquid, thereby producing metal particles and salt, removing unreacted reducing metal, optionally removing the salt, and recovering the metal powder, is described. A method for producing a metal masterbatch wherein the molten reducing metal is aluminum, magnesium, and/or titanium and after combining molten aluminum (or magnesium or titanium) and metal halide in the reaction space, substantially removing the produced metal salt to obtain the metal masterbatch which comprises at least a portion of the molten aluminum (or magnesium or titanium) and at least one metal also is described.

Abstract
The present invention is directed to a method of manufacture of metal or alloy powders that uses liquid phase reduction of a metal halide, or a mixture of metal halides, to produce a metal particle coated in salts produced as a reaction byproduct. The reaction conditions can be chosen to select a range of metal particle sizes, and the salt coating prevents oxidation (or reaction with other atmospheric gases) and permits a range of applications hitherto difficult to achieve using metal powders.

Abstract
Disclosed is a process to reduce mixtures of at least one metal halide by molten metal reduction of the liquid phase metal halide in an alkali or alkaline earth metal to form a reaction product comprising at least one metal mixture and a halide salt coating, in which the at least one metal halide is in stoichiometric excess to the molten metal reductant and wherein the reductant is consumed in the reaction and does not need to be removed at the end of the reaction.
