CHEMISTRY/PHYSICS Transition metal oxides with a cubic perovskite structure display a range of interesting and desirable properties such as piezoelectricity, ferroelectricity, and magnetoresistance. Although most studies have been of thin films or bulk single crystals, preparation of these materials in a one-dimensional form, like their silicon- and ...

Trends in Stability of Perovskite Oxides
Angewandte Chemie International Edition, 2010Perovskite oxides with general formula AMO3 have a large variety of applications as dielectrics and piezoelectrics, ferroelectrics and/or ferromagnetic materials, among others. Rare earth and alkaline earth metal perovskites are useful as catalysts for hydrogen generation, as oxidation catalysts for hydrocarbons, and as effective and inexpensive ...

Oxygen-deficient barium lead oxide perovskites
Physical Review B, 1993Through careful selection of reduction conditions it is found that both BaPbO 3 and Ba 4 Pb 3 O 10 can be prepared with significant amounts of oxygen deficiency. In both cases, crystallographic unit cells and resistivities change with oxygen content.

Complete oxidation of methane over perovskite oxides
Catalysis Letters, 1988The complete oxidation of methane is of significant importance not only for exhaust emission treatment, but also for tunnel cleaniless. In the recent years, many interesting attempts have been focused on this topics. As well known, for the mentioned reaction perovskite oxides have also been suggested.

Properties of Perovskites and Other Oxides
2010In this book some 50 papers published by K A Müller as author or co-author over several decades, amplified by more recent work mainly by T W Kool with collaborators, are reproduced. The main subject is Electron Paramagnetic Resonance (EPR) applied to the study of perovskites and other oxides with related subjects.

Crystal structure and important functions of inorganic perovskite oxides are introduced. Perovskite oxides comprise large families among the structures of oxide compounds, and several perovskite-related structures are currently recognized. Typical structures (ABO3) consist of large-sized 12-coordinated cations at the A-site and small-sized 6 ...

Compressibility of CaZrO3 perovskite: Comparison with Ca-oxide perovskites
Journal of Solid State Chemistry, 2003Abstract The evolution of the unit-cell parameters of CaZrO3 perovskite, an orthorhombic perovskite belonging to space group Pbnm, have been determined to a pressure of 8.7 GPa at room temperature using single-crystal X-ray diffraction measurements. A fit of a third-order Birch–Murnaghan equation of state to the pressure–volume data yields values of ...

Catalytic CO oxidation over manganese-containing perovskites
Environmental Monitoring and Assessment, 1991Mixed metal oxides are discussed as possible substitutes for noble metals in automobile catalytic converters. The catalytic activity for CO oxidation of LaMnO3 and La0.5Sr0.5MnO3 catalysts was examined.The ability of these catalysts to provide lattice oxygen and to sustain the oxidation reaction, even in the absence of molecular oxygen, has been ...

Co oxidation on LaCoO3 perovskite
Korean Journal of Chemical Engineering, 1994A study of CO oxidation on LaCoO3 perovskite was performed in an ultrahigh vacuum system by means of adsorption and desorption. All gases were adsorbed at ambient temperature. Two adsorption states (α- and β-) of CO exist. The α-peak at 440 K is attributed to carbonyl species adsorbed on Co3+ ions while the β-peak at 663 K likely comes from bidentate ...

Introduction to Perovskite Oxides
2019Perovskite, with the chemical formula CaTiO\(_3\), was discovered in 1839 in the Urals. It has a structure consisting of a cage of six oxygen anions surrounding the titanium cation in an octahedron.
