Electrocaloric effect in Pb-free Sr-doped BaTi 0.9 Sn 0.1 O 3 ceramics
Source abstract
Abstract
Abstract Perovskite-type Ba 1− x Sr x Ti 0.9 Sn 0.1 O 3 ( x = 0, 0.06, 0.07, and 0.08) oxides were prepared by conventional solid-state synthesis, and their electrocaloric effect was investigated, revealing that doping by Sr reduces the Curie temperature to ambient values. The largest electrocaloric strength of 0.31 K mm kV −1 was obtained for x = 0.06 at 47 °C, significantly exceeding values displayed by other lead-free ceramics and implying that novel Sr-doped Ba 1− x Sr x Ti 0.9 Sn 0.1 O 3 ceramics are promising materials for ecofriendly refrigeration applications.
