Abstract
The rotostrictive coefficient of F R(LT)− F R(HT) phase transition in the rhombohedral Pb(Zr,Ti)O 3 (PZT) has been evaluated. Using a phenomenological thermodynamic formalism a shift of the thermodynamically stable phase fields of PZT under hydrostatic pressure has been predicted. The para-ferroelectric transition temperature increases, the F R(LT)– F R(HT) transition temperature decreases, and the composition of the morphotropic phase boundary (MPB) moves towards the tetragonal phase field with increasing tensile hydrostatic pressure. Contrary to these, opposite trends were predicted with increasing compressive pressure. Three-dimensional phase diagrams of PZT system using composition, pressure and temperature as the three independent thermodynamic variables have been computed.
