  • Thermoelectric alloy, method for producing the same and thermoelectric alloy composite
    Patent number: 10975456
    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.
