Outline of Final Research Achievements

The flash synthesis was applied to synthesis of a nano powder metal oxide. The nonstoichiometoric oxide thermoelectric materials which were made using these nanoparticles as raw materials, and their fabricating process were studied. And, we proposed the optimal p- and n-type thermoelectric semiconductor as a cascade module from middle temperature to high temperature region. Moreover, the optimal solidification fabrication method of these metal oxide powder was clarified.
