ANTIMONY-DOPED THERMOELECTRIC SOLID SOLUTION MATERIALS AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to an antimony-doped thermoelectric material of a solid solution state and a method for manufacturing the same and, more specifically, to an antimony-doped thermoelectric material of a solid solution state which can improve thermoelectric performance and a method for manufacturing the same. The present invention may significantly improve thermoelectric performance by manufacturing the thermoelectric material of the solid solution state naturally by applying a solid state reaction method after mixing a raw material powder. Furthermore, a molded product having desired density can be manufactured by applying hot compression process in an optimum condition. The present invention has an advantage of manufacturing the thermoelectric material having improved function with a low price by manufacturing the thermoelectric material of the solid solution state only with a process of reacting the raw material powder in a solid state after mixing the raw material. Accordingly, electrical conductivity and Seebeck coefficient of the thermoelectric material may be optimized by doping Sb to the thermoelectric material of a solid solution state.
