Abstract
Disclosed is a method of making a eutectic mixture of copper and tricopper phosphide by reacting elemental copper with phosphine. The elemental copper is heated to a temperature above about 714.degree. C. and the liquid eutectic mixture runs off of the cooper as it is formed, exposing more copper for reaction. The liquid eutectic mixture can be used as a source of copper and phosphorus in making metal alloys.
