N. Cereceda et al., Investigation of the character of the phase transitions in Nb doped Zr-rich PZT by pyroelectric and dielectric measurements, J EUR CERAM, 19(6-7), 1999, pp. 1201-1206
We present a sturdy of the character of the phase transitions of the solid
solution PbZr1-xTixO3. Using the spontaneous polarization curves we determi
ned the mean-field parameters. These parameters show the first order charac
ter of the phase transitions for the richer Zr content and its evolution wi
th composition. The F-RL-F-RH phase transition presents also first order ch
aracter for high contents of Zr. The study of the thermal hysteresis, and t
he jump of the spontaneous polarization, allowed us to investigate this pha
se transition with composition. (C) 1999 Elsevier Science Limited. All righ
