The structure refinement from x-ray diffraction data on PbTiO3 single crystals revealed that the parameters of the mean thermal displacements for Pb ions in the high temperature paraelectric phase (SG ) showed large values. Therefore models with disp

The structure refinement from x-ray diffraction data of PbZrO3 single crystals revealed that the parameters of the mean thermal displacements for Pb ions in the high-temperature paraelectric phase (SG Pm3m) showed unrealistically large values. Theref

The ceramics of new solid solutions of Ag1-xNaxNbO3 (ANN) have been sintered for the whole concentration range. Low frequency dielectric investigations (120-800 K) and DTA investigations (290-600 K) revealed a series of phase transitions. Two predomi

X-ray diffraction measurements showed that in the surface layer of perovskite structure BaTiO3, SrTiO3, PbTiO3 and KNbO3 crystals at elevated temperatures (500–1000°C) reactions take place in the solid phase, associated with segregation in the dir

X-ray investigations of Na05Bi0.5TiO3 crystals showed the coexistence of rhombohedral and tetragonal phases in the wide temperature range. The temperature dependence of phase concentrations can explain the anomaly of dielectric properties observed at

The electric permittivity of ceramic NaNbO3: x Mn (x=0-1 wt.%) was measured in the range 20-500 degrees C. The Mn dopant induces an additional anomaly in the epsilon (T). The temperature of the maxima in epsilon (T) is shifted under applied axial pre
