چکیده
The evolution of the crystal structure (1-x) PbFe2 / 3W1 3O3 - хPbTiO3 solid solutions depending on PbTiO3concentrations (at x = 0.25, 0.3, 0.35) in region morphotropic phase boundary was studied using x-ray diffraction at room temperature. It established that all three compositions are a mixture cubic and tetragonal phases, an increase concentration PbTiO3 above 30 mol. % leads to contribution. parameters content both phases these determined. shown temperature there static displacements lead ions from principle crystallographic positions.

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...

We have monitored the phase transformation from a Sandia octahedral molecular sieve Na2Nb2O6−H2O to a piezoelectric NaNbO3 nanowire through in situ X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements at high temperatures. After dehydration at 288 °C, the Na2Nb2O6−H2O becomes significantly destabilized and transforms into NaNbO3 with the increase of time. The phase tr...
