Аннотация
The structural and electrophysical characteristics of a number of solid solutions of layered perovskite-like oxides Bi3–xYxTiNbO9 (x = 0, 0.1, 0.2, 0.3) have been studied. According to the data of powder X-ray diffraction, all the compounds are single-phase with the structures of two-layer Aurivillius phases (m = 2) with the orthorhombic crystal lattice (space group A21am). The temperature dependence of the relative permittivity ε/ε0(T) compounds have been measured and showed that the Curie temperature of the perovskite-like oxides Bi3–xYxTiNbO9 linearly increases with the substituting parameter x up to TC = 965°C.
