METHOD OF PRODUCING THERMOELECTRIC MATERIAL BASED ON CuSe Russian patent published in 2025 - IPC B22F3/23 C01B19/04 H10N10/01 H10N10/852 H10N10/855

Abstract RU 2833588 C1

FIELD: powder metallurgy.

SUBSTANCE: invention relates to powder metallurgy, particularly to a method of producing thermoelectric material based on copper selenide Cu₂Se. It can be used for thermoelectric generators of medium temperature range. Thermoelectric material based on Cu₂Se with addition of SiC is obtained by self-propagating high-temperature synthesis at argon pressure of 0.5 MPa from a mixture containing, wt.%: copper 61.4 or 58.6, selenium 38.1 or 36.4, silicon carbide 0.5 or 5.

EFFECT: simplified process, reduced power consumption and improved thermoelectric characteristics of obtained material.
