| Résumé: | The study of the anelastic behaviour versus temperature at medium and low frequencies for
undoped and doped lead zirconatetitanate –PZT- reveals the presence of two peaks P1and P2.
According to the phase diagrams established for PZT materials, P1peak could be related to the Curie
transition between tetragonal ferroelectric phase and the cubic paraelectric phase, whereas the P2
peak could be related to the morphotropic phase transition between rhombohedral and tetragonal
ferroelectric phases. Both P1and P2peaks evolutions are in accordance with several existing literature
models for explaining the first order phase transition. The introduction of potassium and niobium
dopants changes the nature of the phase transition process. |
