Title:
METHOD FOR PREPARING THERMOELECTRIC THICK FILM
Document Type and Number:
WIPO Patent Application WO/2021/189602
Kind Code:
A1
Abstract:
A method for preparing a thermoelectric thick film, comprising: determining a brittle-plastic transition temperature of a thermoelectric material; rolling a bulk thermoelectric material in a temperature range between a brittle-plastic transition temperature thereof or more and a melting point thereof or less, in which parameters of the rolling treatment comprise: a linear speed of a roller of 0.01 to 10 mm/s, and preferably 0.1 to 5 mm/s, and a pressing amount of pressing roller at each time controlled to be 0.0005 to 0.1 mm, and preferably 0.001 to 0.05 mm; repeating the rolling treatment until a thermoelectric thick film having a predetermined thickness is obtained; and annealing the resulting thermoelectric thick film; the annealing treatment temperature is 100 to 800 °C, and preferably 300 °C to 500°C; and the annealing treatment is performed for 10 to 500 hours, and preferably 100 to 300 hours.
