ABSTRACT This invention is generally directed to a process for the preparation of chalcogenide alloys of the elements of Groups VA to VIA of the Periodic Table, in high purity, (99.999 percent) which comprises providing pure esters of the alloys desired, and subsequently simultaneously subjecting the esters to a coreduction reaction. The esters can be obtained by treating the corresponding oxides with an alcohol or diol. Examples of alloys produced in accordance with the process of the present invention include selenium arsenic, selenium sulfur selenium tellurium, selenium tellurium arsenic, selenium sulfur tellurium, and the like.
