Abstract
A method of producing an elemental material or an alloy thereof from a halide or mixtures of halides is provided. The halide or mixtures thereof are contacted with a reducing gas in the presence of reductant material, preferably in sufficient quantity to convert the halide to the elemental material or alloy and to maintain the temperature of the reactants at a temperature lower than the boiling point of the reductant material at atmospheric pressure or the sintering temperature of the produced elemental material or alloy.
