摘要:
A conductive paste for connecting thermoelectric conversion material characterized by containing a specific oxide powder and at least one conductive metal powder selected from a group of gold, silver, platinum and an alloy containing at least one of these metals. By connecting a thermoelectric conversion material to a conductive substrate using the conductive paste, an optimum conductivity is given to the connecting portion of a thermoelectric conversion device. Further, it is possible to approximate the thermal expansion coefficient of the connecting portion to that of the thermoelectric conversion material. Therefore, even when power generation at high temperature is repeated, separation of the connecting portion is prevented, and the favorable thermoelectric conversion performance can be maintained.

摘要:
The present invention provides an electrically conductive paste for connecting thermoelectric materials, the paste comprising a specific powdery oxide and at least one powdery electrically conductive metal selected from the group consisting of gold, silver, platinum, and alloys containing at least one of these metals. By connecting a thermoelectric material to an electrically conductive substrate with the electrically conductive paste of the invention, a suitable electroconductivity is imparted to the connecting portion of the thermoelectric element. Further, the thermal expansion coefficient of the connecting portion can be made close to that of the thermoelectric material. Therefore, even when high-temperature power generation is repeated, separation at the connecting portion is prevented and a favorable thermoelectric performance can be maintained.
