Title:

METHOD FOR MANUFACTURING BI-TE-BASED THERMOELECTRIC MATERIAL WITH CONTROLLED DEGREE OF OXIDATION

Document Type and Number:

WIPO Patent Application WO/2018/097399

Kind Code:

A2

Abstract:

The present invention relates to a method of preparing a Bi-Te-based thermoelectric material. More specifically, the present invention provides a novel preparation method wherein metal ribbons formed through rapid solidification process (RPS) are pulverized into a predetermined shape and size under an inert atmosphere, followed by sintering, thereby maintaining a reduction in thermal conductivity, a high Seebeck coefficient, and electrical conductivity through the control of the degree of oxidation, thus improving thermoelectric characteristics.
