P-TYPE HIGH-PERFORMANCE THERMOELECTRIC MATERIAL WITH REVERSIBLE PHASE CHANGE AND PREPARATION METHOD THEREFOR |
| 摘要 |
The present invention relates to a P-type high-performance thermoelectric material featuring reversible phase change, and a preparation method therefor. The thermoelectric material has a chemical composition of Cu2Se1-xIx, wherein 0<x≦0.08. The method comprises: weighing elemental copper metal, elemental selenium metal, and cuprous iodide according to the molar ratio (2−x):(1−x):x, and packaging them in a vacuum; raising the temperature to 1150-1170° C. in stages and performing a melting treatment for 12-24 hours; lowering the temperature to 600-700° C. in stages and then performing an annealing treatment for 5-7 days, the substances being cooled to room temperature in a furnace after the annealing treatment; and performing pressure sintering at 400-500° C. |
