Abstract
The present invention relates to a thermoelectric alloy and a method for producing the same. A starting material is firstly provided, and an oxidation process is performed to the starting material to obtain an oxidized material composition. Then, the oxidized material composition and a carburizing agent are added into a quartz tube, and a sealing process is performed to the quartz tube. And then, the sealed quartz tube is subjected to a carburization process, thereby obtaining the thermoelectric alloy with excellent thermoelectric figure-of-merit.
Claims7
A method for producing a thermoelectric alloy, comprising:
- providing a starting material, wherein the starting material includes germanium (Ge), tellurium (Te), bismuth (Bi), zinc (Zn), antimony (Sb), selenium (Se), copper (Cu), indium (In), gallium (Ga), silver (Ag), cobalt (Co), iron (Fe) and/or lead (Pb);
- performing an oxidation process to the starting material for producing an oxidized material composition, wherein based on the oxidized material composition as 100 atom percent (at %), an oxygen content of the oxidized material composition is 0.001 at % to 10 at %;
- adding the oxidized material composition and a carburizing agent into a quartz tube, and performing a sealing process, so as to form a sealed quartz tube;
- and
- performing a carburization process to the sealed quartz tube, thereby producing the thermoelectric alloy.
