Misfit-layered cobaltite Ca3Co4O9+δ is considered as good p-type thermoelectric material in high temperature region (950 - 1100 K), while half-Heusler (HH) Ti0.3Zr0.35Hf0.35CoSb0.8Sn0.2 is high performance p-type material at temperatures below 950 K. In this work, oxide Ca3Co4O9+δ is segmented with HH using an electrically conductive adhesive and brazing joining technique. The thermoelectric properties of the component materials as well as the interfacial resistance at high temperatures were characterized as a function of temperature up to 1100 K, and the results are discussed in details.
