Abstract

In this paper, w/o-microemulsions were employed to produce nanoparticles of the perovskite Ca{sub 0.5}Sr{sub 0.5}MnO{sub 3}, which have a size of approximately 20-50 nm. The procedure was carried out using sodium hydroxide or ammonia as co-precipitation agent. The precursor was transformed to perovskite by calcinations at 580 deg. C. Nanosized particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and N{sub 2} adsorption (BET)

Hydrothermal synthesis of the perovskite manganites Pr{sub 0.5}Sr{sub 0.5}MnO{sub 3} and Nd{sub 0.5}Sr{sub 0.5}MnO{sub 3} and alkali-earth manganese oxides CaMn{sub 2}O{sub 4}, 4H-SrMnO{sub 3}, and 2H-BaMnO{sub 3}

Journal Article Spooren, Jeroen ; Walton, Richard I. - Journal of Solid State Chemistry

We report the synthesis of the perovskite manganites Pr{sub 0.5}Sr{sub 0.5}MnO{sub 3} and Nd{sub 0.5}Sr{sub 0.5}MnO{sub 3} using mild hydrothermal conditions. Both are formed as polycrystalline powders from solutions of metal salts in aqueous potassium hydroxide at 240 deg. C, and crystallise as a tetragonal polymorph (space group I4/mcm). Scanning electron microscopy shows both materials to contain cuboid-shaped crystallites several microns in dimension, and the average particle size is verified by light scattering measurements. We also report the first hydrothermal synthesis of 2H-BaMnO{sub 3} and 4H-SrMnO{sub 3}, and the first subcritical hydrothermal synthesis of CaMn{sub 2}O{sub 4} (marokite). Despite themore »« less

Neutron diffraction study of phase separation in the Pr{sub 0.5-{delta}}Ca{sub 0.2+{delta}}Sr{sub 0.3}MnO{sub 3} manganite around half doping

Journal Article Aurelio, G. ; Niebieskikwiat, D. ; Sanchez, R.D. ; ... - Physical Review. B, Condensed Matter and Materials Physics

This article studies the intrinsic influence of hole doping (n=0.5+{delta}) on the structural and magnetic phases of the Pr{sub 0.5-{delta}}Ca{sub 0.2+{delta}}Sr{sub 0.3}MnO{sub 3} ceramic manganite. Neutron thermodiffractograms are reported for samples with n=0.46, 0.48, 0.50, 0.52, and 0.54 ({delta}=-0.04,-0.02,0.0,0.02,0.04) in the temperature range 10 K{<=}T{<=}300 K, as well as high-resolution neutron-diffraction experiments for selected samples and temperatures. We observe structural and magnetic phase coexistence for all the studied compositions and discuss the temperature evolution of the lattice parameters, phase fractions, and magnetic moments of the observed phases. For hole dopings n<(1/2), the ground state at low temperature is ferromagnetic, whilemore »« less

Journal Article Porob, Digamber G. ; Guru Row, T.N. - Journal of Solid State Chemistry

Two new compounds Ca{sub 0.5}Bi{sub 3}V{sub 2}O{sub 10} and Sr{sub 0.5}Bi{sub 3}V{sub 2}O{sub 10} have been synthesized in the ternary system: MO-Bi{sub 2}O{sub 3}-V{sub 2}O{sub 5} system (M=M{sup 2+}). The crystal structure of Sr{sub 0.5}Bi{sub 3}V{sub 2}O{sub 10} has been determined from single crystal X-ray diffraction data, space group P1-bar and Z=2, with cell parameters a=7.1453(3)A, b=7.8921(3)A, c=9.3297(3)A, {alpha}=106.444(2){sup o}, {beta}=94.088(2){sup o}, {gamma}=112.445(2){sup o}, V=456.72(4)A{sup 3}. Ca{sub 0.5}Bi{sub 3}V{sub 2}O{sub 10} is isostructural with Sr{sub 0.5}Bi{sub 3}V{sub 2}O{sub 10}, with, a=7.0810(2)A, b=7.8447(2)A, c=9.3607(2)A, {alpha}=106.202(1){sup o}, {beta}=94.572(1){sup o}, {gamma}=112.659(1){sup o}, V=450.38(2)A{sup 3} and its structure has been refined by Rietveld methodmore »« less

Journal Article Biendicho, J.J. ; The ISIS Facility, STFC Rutherford Appleton Laboratory, Didcot, OX11 0QX Oxfordshire ; Shafeie, S. ; ... - Journal of Solid State Chemistry

Oxygen-deficient ferrates with the cubic perovskite structure Sr{sub x}Y{sub 1−x}FeO{sub 3−δ} were prepared in air (0.71≤x≤0.91) as well as in N{sub 2} (x=0.75 and 0.79) at 1573 K. The oxygen content of the compounds prepared in air increases with increasing strontium content from 3−δ=2.79(2) for x=0.75 to 3−δ=2.83(2) for x=0.91. Refinement of the crystal structure of Sr{sub 0.75}Y{sub 0.25}FeO{sub 2.79} using TOF neutron powder diffraction (NPD) data shows high anisotropic atomic displacement parameter (ADP) for the oxygen atom resulting from a substantial cation and anion disorder.

Synthesis and properties of Ba{sub 0.5}Sr{sub 0.5}(Co{sub 0.6}Zr{sub 0.2})Fe{sub 0.2}O{sub 3-{delta}} perovskite cathode material for intermediate temperature solid-oxide fuel cells

Journal Article Meng Xiuxia ; Meng Bo ; Tan Xiaoyao, E-mail: cestanxy@yahoo.com.cn ; ... - Materials Research Bulletin

A highly stable perovskite cathode material, Ba{sub 0.5}Sr{sub 0.5}(Co{sub 0.6}Zr{sub 0.2})Fe{sub 0.2}O{sub 3-{delta}} (BSCZF) for intermediate temperature solid-oxide fuel cells (IT-SOFCs) was synthesized via the improved EDTA-citric acid complexing technique combined with high-temperature sintering. The product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectra (EIS) measurements. An electrolyte-supported BSCZF/SDC/Ni-SDC fuel cell was fabricated to evaluate the performance of the material. The XRD study indicates that the sintering temperature higher than 950 deg. C is sufficient to the formation of clean single BSCZF perovskite phase. Due to the incorporation of Zr ions, BSCZF perovskite exhibitmore »« less
