Calcium And Rare-earth Metal Mixed Zintl Phase Compounds And Manufacturing Method Thereof

摘要

The previously reported tri-component compound Ca ₂ CdSb ₂ was expected to be utilized as a thermoelectric material, but thermoelectric properties other than the reported crystal structure were never reported. In the present invention, by partially substituting calcium (Ca) in the three-component gentle compound with rare-earth metals ytterbium (Yb) and europium (Eu), a four-component gentle compound with increased structural complexity and mass is synthesized to achieve thermoelectric properties. Improved. In addition, by synthesizing various four-component jingle compounds, the change in thermoelectric properties according to the type and substitution ratio of rare earth metals was experimentally confirmed. Therefore, the four-component Jintle compound of the present invention has thermoelectric performance and can be used as a thermoelectric material, and it is expected that various kinds of Jintle compounds for thermoelectric materials can be synthesized by using the phase change mechanism and manufacturing method of the four-component Jintle compound of the present invention. .
