Single-phase ceramic samples from the region of morphotropic phase boundary in the (1–x)(Na0.5Bi0.5)TiO3–xBaTiO3 and (1–y)[(Na0.5Bi0.5)TiO3–xBaTiO3]–yBi(Mg0.5Ti0.5)O3 systems, modified by low-melting LiF and 0.6NaCl–0.4LiF additives, have been prepared by solid-state synthesis. The effect of additives on the phase formation, structural parameters, and dielectric and ferroelectric properties of the ceramics has been studied. A decrease in the ceramic sintering temperature is found. A slight increase in the unit-cell volume upon modification of the ceramics under study by lithium fluoride and 0.6NaCl–0.4LiF additive is revealed. First-order ferroelectric phase transitions near 700–800 K have been observed. The prospects for improving the piezoelectric properties of modified ceramic samples are proved.
