The system of (Na_0.5Bi_0.5)TiO₃-BaTiO₃ solid solutions has attracted considerable interest due to its promising electromechanical, electrocaloric, and energy storage properties. In this work, the effect of LiF additive on the ferroelectric properties of 0.8(Na_0.5Bi_0.5)TiO₃-0.2BaTiO₃ ceramics is investigated. The samples were prepared by the conventional solid state synthesis technology. The LiF content varied from 0 to 15 mol
