Nonstoichiometry of the perovskite-type solid solution La0.9Ca0.1Cr1−Al O3−

Solid State Ionics, 2006
Abstract Nonstoichiometry of the perovskite-type solid solutions La0.9Ca0.1Cr1−yAlyO3−δ was studied by high-temperature gravimetry under controlled P(O2) atmospheres of 1–10− 23 bar at 1073–1273 K. The observed data were described by a regular solution-like model for the randomly distributed defects of VO¨ , CrCr. , CaLa,, and AlCrX.

Phase transitions in ferroelectric solid solutions of complex perovskites

Ferroelectrics, 1989
Abstract The phenomenological theory of ferro- and antiferroelectric solid solutions is proposed taking into account the possibility of compositional order variation. Complex perovskites AB′0.5B″0.5O3 where one of the cations is substituted are considered.

Catalytic oxidation of CO on LaMn1−xFexO3 perovskites solid solution

Journal of Molecular Catalysis A: Chemical, 2014
Abstract Catalytic CO oxidation was studied over LaMn1−xFexO3 perovskites prepared by co-precipitation and rotor-vapor citrate method. The catalysts were characterized by X-ray diffraction (XRD), Transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS).

Study of PbZr0.53Ti0.47O3 solid solution formation by interaction of perovskite phases

Journal of the European Ceramic Society, 2007
Abstract The formation of Pb(Zr0.53Ti0.47)O3 solid solution around the MPH was studied by mutual interaction of perovskite PZT phases (rhombohedral and tetragonal) and by interaction of PZT phases with PbTiO3 or PbZrO3 at sintering temperature.

Perovskite solid solutions in the BaO-CuO-Y2O3-Nb2O5 system

Solid State Sciences, 1999
Abstract Freeze dried complex carboxylates are highly reactive precursors for complex perovskite solid solutions in the system BaO-CuO-Y2O3-Nb2O5 On thermal decomposition of the amorphous precursors the formation of complex crystalline phases begins at 600 °C. In most cases the themodynamically controlled phase composition is reached after a reaction
