Synthesis and thermoelectric properties of ceramics based on barium-strontium metaplumbates



Ceramics with composition Ba1 − x Sr x Pb1 + y O3 + 2y (x = 0.6, 0.8; y = 0.0, 0.1, 0.2) was synthesized by solid-state method; its phase composition, crystal structure, and thermal, electrophysical, and thermoelectric properties were studied. The electronic and lattice contributions to thermal conductivity of the ceramics were separated; the linear thermal expansion coefficient (LTEC, α), power factor (P), and thermoelectric quality factor (ZT) were calculated. Ceramics with composition Ba0.2Sr0.8Pb1 + y O3 + 2y (P 1000 = 1.36 mW m−1 K−2 for y = 0.1, ZT 423 = 0.033 for y = 0.2) containing lead oxide impurity, in addition to the major phase (barium-strontium metaplumbate), was found to possess the best thermoelectric properties.
