METHOD FOR SINTERING THERMOELECTRIC MATERIALS

摘要

The method for producing, processing, sintering, pressing or extruding thermoelectric materials under heat treatment using an inert gas, or at a reduced pressure at temperatures ranging from 100 to 900 °C is characterised in that the producing, processing, sintering, pressing or extruding is carried out in the presence of oxygen scavengers which form thermodynamically stable oxides under the producing, processing, sintering, pressing or extrusion conditions in the presence of free oxygen and thus keep free oxygen away from the thermoelectric material.
