| Research Abstract |
The possibility of production of FeSi2 thermoelectric conversion module by spark plasma sinter-joining method was examined. In addition, the thermoelectric conversion characteristics was evaluated by using the module processed in various kinds of shape. It was clarified that the p-n joining with sintering from powder was possible by spark plasma sinter-joining method. The module with excellent thermoelectric conversion characreristics was obtained by the direct joining further than the sinter-joining. The Seebeck coefficient showed a high value of 0.62mV/K when it measured temperature difference and thermoelectomotive force by the modules. This was equal with a value of the p-n indirect joining module. This Seebeck coefficient was high value than 0.1mV/K which was already reported. In addition, it was made dear that the Seebeck coefficient depended on the shape of module.
