- Аннотация: The phase formation, specific features, and the dielectric properties of the ceramics of compositions from the region of morphotropic interface in the (Na0.5Bi0.5)TiO3-BaTiO3 system modified by Bi(Mg0.5Ti0.5)O-3 and also low-melting additions KCl, NaCl-LiF, CuO, and MnO2 that favor the control of the stoichiometry and the properties of the ceramics have been studied. The ceramics are characterized by ferroelectric phase transitions that are observed as jumps at temperatures near 400 K and maxima at T (m) similar to 600 K in the temperature dependences of the dielectric permittivity. The phase transitions at similar to 400 K demonstrate the relaxor behavior indicating the existence of polar domains in the nonpolar matrix. An increase in the content of Bi(Mg0.5Ti0.5)O-3 favor a decrease in the electrical conductivity and dielectric losses of the samples, and the relative dielectric permittivity at room temperature epsilon(rt) is retained quite high, achieving the highest values epsilon(rt) = 1080-1350 in the ceramics modified with KCl.
