放電プラズマ焼結法により焼結・接合したFeSi₂熱電変換センサーの熱応答特性

抄録

FeSi₂ thermoelectric conversion materials are known for their high resistance to corrosion and heat; deposits of these materials are also plentiful and they have a low environmental impact. For this reason, extensive research has been carried out on FeSi₂ thermoelectric conversion materials for power generation. In order to extend its application range, the authors tested the use of a sensor made of FeSi₂. It is possible to use FeSi₂ in fire sensors because it can be used to detect the voltage produced due to a change in the temperature. The present study examined the thermo-electromotive force of FeSi₂ and its thermo-responsiveness in order to assess whether it has functional properties for use in fire sensors. The influence of module dimensions on thermo-electromotive force and thermal responsiveness was also examined.
