THERMO-ELECTRIC MATERIAL AND PROCESS OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To solve the problem in which reduction in conductivity is expected caused by a PTCR (Positive Temperature Coefficient of Resistivity) effect at a grain boundary inside a sample in the vicinity of a Curie temperature (T: 60 to 200°C depending on a composition) of SBN, supposing...

Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem in which reduction in conductivity is expected caused by a PTCR (Positive Temperature Coefficient of Resistivity) effect at a grain boundary inside a sample in the vicinity of a Curie temperature (T: 60 to 200°C depending on a composition) of SBN, supposing SBN a polycrystal in view of element applications.SOLUTION: The thermo-electric material that is a ceramic reductant exhibiting thermoelectric characteristics by reducing a tungsten bronze type metal oxide, having high conductivity in a relatively high temperature range can be provided.
