EXTRUSION PROCESS FOR PREPARING IMPROVED THERMOELECTRIC MATERIALS |
摘要 |
<p>With respect to a method for reducing the thermal conductivity and for increasing the thermoelectric efficiency of thermoelectric materials based on lead chalcogenides or skutterudites, the thermoelectrical materials are extruded at a temperature below their melting point and a pressure in the range of 300 to 1000 MPa.</p> |
