Synthesis and characterization of complex perovskite solid solutions.

open access: yes, 2010
Materials based on the solid solution of (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 ((1-x)PMN-xPT) show some of the best piezoelectric and ferroelectric properties. Although the ferro-/piezoelectric properties are very good, there are drawbacks to this system such as difficulty in preparing pure phase ceramics and low operating temperature range resulting from the ...

Mechanism of Solid Solution and Crystal Chemistry in MgSiO3-FeAlO3 Perovskite

open access: yesNihon Kessho Gakkaishi, 2011
MgSiO3 dominant perovskite is believed to be the most abundant constituent mineral in the Earth’s lower mantle. Generally minerals form solid solutions and their nature should affect on physical properties of minerals. In this paper, we will introduce our recent studies about incorporation mechanism of FeAlO3 component into MgSiO3 perovskite and its ...

Vibrational spectra of solid solution series with ordered perovskite structure [PDF]

open access: yesJournal of Inorganic and Nuclear Chemistry, 1975
I.R. and Raman spectra are reported for the following three systems: Ba2CaMo1−xTexO6, Ba2−xSrxMgWO6 and Ba2Ca1−xMgxWO6. In the first series the internal vibrations of the M6+O6 octahedra do not influence each other. The intensity of ν1 (MoO6) is five times that of ν1 (TeO6).

Evaluation of covalency of ions in lead-free perovskite-type dielectric oxides

open access: yesAIP Advances, 2017
Electronic states of ions in lead-free perovskite-type dielectric oxides have been investigated with a first-principle cluster calculation. For this calculation a double-perovskite cluster model based upon the simple cubic ABO3 was used; A and B are both

Structure and cation distribution in perovskites with small cations at the A site: the case of ScCoO3

open access: yesScience and Technology of Advanced Materials, 2015
We synthesize ScCoO3 perovskite and its solid solutions, ScCo1−xFexO3 and ScCo1−xCrxO3, under high pressure (6 GPa) and high temperature (1570 K) conditions. We find noticeable shifts from the stoichiometric compositions, expressed as (Sc1−xMx)MO3 with x
