摘要

Perovskite-type Ba_1−xSr_xTi_0.9Sn_0.1O₃ (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−xSr_xTi_0.9Sn_0.1O₃ ceramics are promising materials for ecofriendly refrigeration applications.
