Relaxor ferroelectric properties of the system

X-ray diffraction, dielectric, piezoelectric, and pyroelectric studies have been performed on ceramic samples of (1 - 2x)BiSc[O.sub.3] * xPbTi[O.sub.3] * xPbM[g.sub.1/3] N[b.sub.2/3] [O.sub.3] (0.30 [less than or equal to] x [less than or equal to] 0.46) perovskite-like solid solutions. The solid so...

Summary:X-ray diffraction, dielectric, piezoelectric, and pyroelectric studies have been performed on ceramic samples of (1 - 2x)BiSc[O.sub.3] * xPbTi[O.sub.3] * xPbM[g.sub.1/3] N[b.sub.2/3] [O.sub.3] (0.30 [less than or equal to] x [less than or equal to] 0.46) perovskite-like solid solutions. The solid solution symmetry was found to vary from the rhombohedral (x [less than or equal to] 0.38) to tetragonal (x [greater than or equal to] 0.42) as x increases. The samples with 0.30 < x [less than or equal to] 0.42 have properties characteristic of relaxor ferroelectrics, namely the existence of a wide peak in the temperature dependence of the dielectric permittivity at [T.sub.m[epsilon] = 390-440 K that shifts to higher temperatures as the frequency increases, narrow unsaturated dielectric hysteresis loops, and an electric field-induced transition to the ferroelectric state at 318 K. The observed features of the dielectric, piezo-, and pyroelectric properties of these solid solutions are explained by the fact that they are relaxor ferroelectrics. DOI: 10.1134/S1063783417010036
