Abstract: The process for producing, processing, sintering, pressing or extruding thermoelectric materials with heat treatment under inert gas or under reduced pressure at temperatures in the range from 100 to 900° C. comprises producing, processing, sintering, pressing or extruding in the presence of oxygen scavengers which form thermodynamically stable oxides in the presence of free oxygen under the production, processing, sintering, pressing or extrusion conditions and hence keep free oxygen away from the thermoelectric material.
