Abstract: 11,415. Kitsee, I. May 9. Filaments of metals such as tungsten and tantalum are made from the corresponding phosphides, which are shaped by squirting or moulding and then reduced by electrolysis, for instance in dilute phosphoric acid with platinum anodes; porous filaments or thick rods of high resistance are obtained, which may be consolidated mechanically. The phosphide may be prepared by adding about one gram atom of phosphorus to four gram atoms of metal previously heated to 800-1000‹ F. in a closed crucible, or by heating the two together. Excess of phosphorus remains uncombined if air is excluded.
