PbSb co-doped BiCuSeO-based thermoelectric material and preparation method thereof
The invention discloses a method for preparing a Pbamp; the invention discloses a Sb co-doped BiCuSeO-based thermoelectric material and a preparation method thereof, and belongs to the technical field of energy conversion. The preparation method comprises the following steps: weighing Bi2O3, Bi, Cu, Se, Pb and Sb powder according to the stoichiometric ratio of Bi0.94-xPb0. 06SbxCuSeO (x is greater than or equal to 0 and less than or equal to 0.035), uniformly mixing in an agate mortar, and obtaining Pbamp by adopting a sample preparation process of high-temperature sintering and annealing; the invention relates to a Sb co-doped BiCuSeO-based thermoelectric material. And grinding the sintered material into powder by using an agate mortar, loading the powder into a graphite mold, and carrying out rapid hot pressing at 600 DEG C and 70 MPa for 30 minutes to obtain the Bi < 0.94-x > Pb < 0.06 > Sb < x > CuSeO block thermoelectric material. According to the thermoelectric material prepared by the invention, the thermal conductivity of Bi0. 94Pb0. 06CuSeO is reduced, and the Seebeck coefficient is remarkably improved, so that the thermoelectric performance of the BiCuSeO-based material is remarkably enhanced.
本发明公开了一种Pb&Sb共掺杂BiCuSeO基热电材料及其制备方法，属于能源转换技术领域。按照Bi0.94‑xPb0.06SbxCuSeO(0≤x≤0.035)的化学计量比称取Bi2O3、Bi、Cu、Se、Pb、Sb粉，在玛瑙研钵中混合均匀，再采用高温烧结、退火的样品制备工艺，获得Pb&Sb共掺杂BiCuSeO基热电材料。用玛瑙研钵将烧结后的材料研磨至粉末状，将粉末装入石墨模具中，在600℃、70 MPa下快速热压30 min，得到Bi0.94‑xPb0.06SbxCuSeO块体热电材料。本发明制备的热电材料降低了Bi0.94Pb0.06CuSeO的热导率，并实现了塞贝克系数的显著提高，从而显著增强了BiCuSeO基材料的热电性能。
