Radiation defects in complex perovskite solid solutions
Nuclear Instruments & Methods in Physics Research B, 2014Abstract First principles density functional theory (DFT) based modeling is performed to explore formation energies of a series of point cation and oxygen defects, Frenkel and Schottky disorder, as well as structural disorder in Ba1−xSrxCo1−yFeyO3−δ (BSCF) perovskite solid solutions.

Proton conductive perovskite solid solutions with enhanced mechanical stability
Solid State Ionics, 1996Abstract Perovskite solid solutions with formula SrYb0.05(Ce1 − xZrx)0.95O3 − α (x = 0, 0.25, 0.5, 0.75 and 1) were prepared. Their electrical behaviour was investigated using impedance spectroscopy between 200 and 1000 °C in different atmospheres, with and without hydrogen. Conductivities and their activation energies were obtained.

DFT Calculations for Some Perovskites and Their Solid Solutions
physica status solidi (b), 2021Herein, ab initio calculations of the electron density of states (DOS) of sodium‐bismuth titanate , potassium‐bismuth titanate , lead titanate and some of their solid solutions are presented. The DOS is calculated and compared with available data, respectively. For all compositions, an energy gap of about 1.6 eV is obtained.

Synthesis of solid solutions of perovskites
Glass and Ceramics, 1985The authors carry out thermographic studies, using a derivatograph, in order to understand the nature of the processes taking place during the synthesis of solid solutions of perovskites. Based on the detailed studies on the phase transformations occurring in the charges of the PSN-PMN solid solutions and on the selection of the optimum conditions for ...

Special quasirandom structures for perovskite solid solutions
Journal of Physics: Condensed Matter, 2016Special quasirandom structures (SQS) are presently generated for disordered (A'1-x [Formula: see text] x )BX3 and A(B'1-x [Formula: see text] x )X3 perovskite solid solutions, with x = 1/2 as well as 1/3 and 2/3. These SQS configurations are obtained by imposing that the so-called Cowley parameters are as close to zero as possible for the three ...

Kinetics of phase transitions in solid solutions of ferroelectric perovskites
Physical Review B, 1995The dynamics of interphase boundaries at first-order phase transitions in ferroelectric solid solutions are considered. The width and velocity of the interphase boundary as functions of concentration are calculated for the ferroelectric perovskite solid solutions K(Ta,Nb)${\mathrm{O}}_{3}$ (KTN) and Pb (Zr,Ti)${\mathrm{O}}_{3}$ (PZT), which are taken ...

Quantum chemical modelling of perovskite solid solutions
Journal of Physics: Condensed Matter, 2000In line with our previous study (Eglitis R I et al 1998 J. Phys.: Condens. Matter 10 6271) for a single Nb impurity and Nb clusters in KTaO3 we present here the results of calculations for a series of perovskite KNbx Ta 1−x O3 (KTN) solid solutions (x = 0, 0.125, 0.25, 0.75, and 1).
