Abstract
The phase formation, structural features, and dielectric, ferroelectric, and piezoelectric properties of ceramics with compositions from the region of the morphotropic phase boundary in the (Na0.5Bi0.5)TiO3–BaTiO3–Bi(Mg0.5Ti0.5)O3 system modified by different low-melting additives (Bi2O3, V2O5, KCl, NaCl–LiF, LiF, CuO, and MnO2) are studied. First-order phase transitions are detected near 700–800 and 400 K that display relaxor behavior and are indicative of the presence of polar regions in a nonpolar matrix. Prospects for improving the piezoelectric properties of the modified ceramic samples are confirmed.
