YBa 2 Cu 3 O 7-x -Ca 3 Co 4 O 9 (YBCO-CCO) segmented ceramic was prepared successfully using a conventional solid state sintering technique. X-ray diffraction patterns and microstructural observation indicated phase purity and a compatibility of YBCO and CCO ceramics. The maximum values of electrical conductivity (σ), Seebeck coefficient (S) and figure of merit (ZT) of YBCO-CCO segmented ceramic were 1.23 × 10 4 Ω −1 m −1 , 179 μV/K and 0.35, respectively. Meanwhile, the thermal conductivity (κ) values of these three compounds were not significantly different and possessed small temperature dependence. The enhancement in the ZT values of YBCO-CCO segmented ceramic at high temperature compared to the conventional CCO ceramic suggested that the former might be used as an alternative p-type material for thermoelectric devices. 2019-03-18T02:22:58Z 2019-03-18T02:22:58Z 2019-01-01 Journal 03615235 2-s2.0-85062710344 10.1007/s11664-019-07105-w https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85062710344&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/63653 |
