Abstract
This paper reports the development of a new bismuth and lead oxide-based high-temperature ferroelectric ternary solid solution xBi(Zn 1/2Ti1/2)O3-yPbZrO3-zPbTiO 3 (xBZT-yPZ-zPT). Structural analysis has been carried out by XRD and SEM. A morphotropic phase boundary (MPB) between rhombohedral and tetragonal phases has been located on a pseudobinary line 0.1BZT-0.9[(1-x)PZ-xPT] within the ternary phase diagram. Dielectric studies of various compositions along the pseudobinary line 0.1BZT-0.9[(1-x)PZ-xPT] have been carried out in a wide range of temperatures from room temperature to 600 C, on both poled and unpoled samples. Compositions near the MPB exhibit high dielectric permittivity (∼23 000-28 000). Rhombohedral compositions show a diffuse phase transition with a small frequency dispersion. Based on the dielectric properties and differential scanning calorimetry, phase transition trends versus composition along the pseudobinary line 0.1BZT-0.9[(1-x)PZ-xPT] have been demonstrated.
