Application filed December 29, 1906. Serial No. 360,081.
Be it known that we, EDGAR F. PRICE, citizen 'of the United States, and \VILLIAM SMITH HoRRY, a subject of Kin of Great county of Niagara and'State of New York,
have invented certain new and useful Irn-- provernents in Electrolytic Processes of Producing Metals, of which the following is a specification.
This process relates to the electrolytic re- A molten bath of calcium chlorid or fluorid, preferably with additions of the correspo mg salts of strontium andammonium to lower the melting point, is el'ectrolyzed with a composite anode of calcium carbid and a binder, any suitable cathode, for example one of. iron, being employed to receive the electro-deposited,calci rmi 'lhegnode gradi 'uallydissolves,the contained calcium recombining with thehalogenion to replenish the bath, while the carbon may float to-the surface and be burned by the atmospheric oxygen." It'is preferred, however; tOXdisf solve cj'aljcium oxid in the electrolyte, in 7 'WlllCl'l case the oxygen ion is liberated at andcombines withthe carbon of the anode,-cor respondingly decreasin the consumption of electric energy, while t. e calcium ion of the oxid isdeposited at the cathode-simultanee ously with that from the haloid salt.
