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.

研究了采用放电等离子体烧结连接法生产FeSi2热电转换模块的可能性。另外，使用加工成各种形状的模块来评价热电转换特性。明确了通过放电等离子体烧结接合法可以通过粉末烧结实现p-n接合。通过比烧结接合更进一步的直接接合，获得了具有优异热电转换特性的模块。当模块测量温差和热电动势时，塞贝克系数显示出高达0.62mV/K的值。这与p-n间接连接模块的值相等。该塞贝克系数比已经报道的0.1mV/K高。此外，值得注意的是，塞贝克系数取决于模块的形状。
