THERMOELECTRIC CONVERSION MATERIAL AND THERMOELECTRIC CONVERTER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a thermoelectric conversion material that is composed of an oxide shown by NaxCoOy(x and y are respectively 0.5≤x≤1 and 1≤y≤2) and excellent in thermoelectric conversion performance.

SOLUTION: The thermoelectric conversion material is obtained by spreading and dissipating fine particles in base material particles after depositing the fine particles made of Na or a compound including Na on the surfaces of the particles, as the base material for the thermoelectric conversion material in a process for manufacturing the thermoelectric conversion material utilizing a complex polymerization method. The fine particles have an average particle size in a range of 0.1-1 μm.
