| Research Abstract |
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 the optimal compositions of p-and n-type thermoelectric semiconductors were determined. Moreover, the optimal solidification fabrication method of these metal oxide powder was clarified.
