Performance Optimization of Pb_0.97La_0.03Sc_0.45Ta_0.45Ti_0.1O₃ Ceramics by Annealing Process.

ABSTRACT: The annealing effects on Pb_0.97La_0.03Sc_0.45Ta_0.45Ti_0.1O₃ (PLSTT) ceramics prepared by the solid-state reaction method are systemically investigated using experimental and theoretical techniques. Comprehensive studies are performed on the PLSTT samples by varying annealing time (AT) from t (=0, 10, 20, 30, 40, 50 and 60) h. The properties involving ferroelectric polarization (FP), electrocaloric (EC) effect, energy harvesting performance (EHP) and energy storage performance (ESP) are reported, compared and contrasted. All these features are seen to gradually improve with the increase in AT, and they all reach the climaxed-shaped values and then decrease by further increasing the AT. For t = 40 h, the maximum FP
