Process for preparation of chalcogenide alloys by solution coreduction of a mixture of oxides

A process for the preparation of a chalcogenide alloy in high purity which comprises providing a solution mixture of selenium oxides and tellurium oxides and subsequently subjecting this mixture to a simultaneous coreduction reaction with hydrazine or sulphur dioxide, thereby resulting in the product Se.sub.89.6 Te.sub.10.4.
