Anomalous reduction in domain wall displacement at the morphotropic phase boundary of the piezoelectric alloy system PbTiO3-BiScO3

, 2016
A comparative study of field-induced domain switching and lattice strain was carried out by in situ electric-field-dependent high-energy synchrotron x-ray diffraction on a morphotropic phase boundary (MPB) and a near-MPB rhombohedral/pseudomonoclinic ...

Synthesis of PZT powder by conventional method at various conditions

EPJ Web of Conferences, 2012
In this work, the formation of Pb(Zr1-xTix)O3 solid solutions with composition near the morphotropic phase boundary (MPB) using the conventional ceramic method have been studied by changing the thermal conditions such as temperature ramp rate and ...

Thermodynamic nature of phase transitions in Pb(Zr_xTi_1-x)O₃ ceramics near the morphotropic phase boundary. I. Structural studies

, 1997
The room-temperature structures of Pb(ZrxTi1-x)O3 ceramics are shown to be tetragonal for x ≤ 0.52 and rhombohedral for x ≥ 0.530 while both the rhombohedral phase (R-phase) and the tetragonal phase (T-phase) coexist at x = 0.525 corresponding to the ...

Effect of stress induced monoclinic to tetragonal phase transformation in the multiferroic (1-x)BiFeO₃-xPbTiO₃ system on the width of the morphotropic phase boundary and the tetragonality

, 2011
The relative stability of the tetragonal and monoclinic phases in the (1-x)BiFeO3-xPbTiO3 solid solution system has been investigated under externally applied stress. It is shown that external stress can transform monoclinic compositions partially to the
