Observation of large electrocaloric properties in lead-free Ba0.98Ca0.02Ti0.98Sn0.02O3 ceramics
Tetragonal lead-free Ba0.98Ca0.02Ti0.98Sn0.02O3 (BCST) compound sintered at 1400 °C was investigated for its electrocaloric properties. The large adiabatic temperature variation, ΔT ∼ 0.476 K and isothermal entropy change, ΔS ∼ 1.90 J/kg.K were obtained at ∼ 373 K at an electric field of 20 kV/cm. F...
