EXTRUSION PROCESS FOR PRODUCING IMPROVED THERMOELECTRIC MATERIALS |
| 摘要 |
<p>For a process for reducing the thermal conductivity and for increasing the thermoelectric efficiency of thermoelectric materials based on lead chalcogenides or skutterudites, the thermoelectric materials are extruded at a temperature below their melting point and a pressure in the range from 300 to 1 000 MPa.</p> |
