ABSTRACT:
This invention is generally directed to a process for preparing chalcogenide alloys of high purity which comprises providing the corresponding pure esters of the elements desired in an organic medium, and an organic salt followed by simultaneously coreducing the esters by an electrochemical reduction in an electrolytic apparatus. More specifically, in one embodiment, selenium arsenic, alloys of high purity are prepared by subjecting the corresponding pure esters to a simultaneous electrochemical reduction reaction in an electrochemical apparatus containing an anode, a cathode, an electrolytic solution comprised of the pure esters of selenium and arsenic, contained in a solution of an organic solvent, and an organic salt wherein the pure esters lose electrons resulting in the desired metallic alloys.
