“…However, the sol-gel process has several disadvantages when employed to prepare PZT ceramics in large quantities: it requires a large quantity of solvent and it is very time-consuming. [7] Mandal and Ram sythesized PbZr 0.7 Ti 0.3 O 3 nanoparticles possessing a new tetragonal crystal structure with a polymeric precursor and polyvinyl alcohol. [1] Zhang et al [7] prepared PZT ceramics derived from a hybrid method between the sol-gel process and the solid-state reaction.…”

A perovskite lead zirconate titanate was synthesized by the sol-gel process, using lead glycolate, sodium tris(glycozirconate) and titanium glycolate as the starting precursors. • C; it transformed to the tetragonal and the cubic forms of the perovskite phase on calcination above the Curie temperature, as verified by X-ray data. The lead zirconate titanate synthesized and calcined at 400• C for 1 h had the highest dielectric constant, the highest electrical conductivity and the dielectric loss tangent of 10 190, 0.803 × 10 −3 ( .m) −1 and 1.513 at 1000 Hz, respectively. The lead zirconate titanate powder synthesized has potential applications as an electronic material.

“…Pb(Zr,Ti)O 3 (PZT), solid solution of PbZrO 3 and PbTiO 3 , has been developed by B. Jaffe [2]. However, plenty of problems and obstacles are remained, such as weak mechanical strength, strong dependence of dielectric property on frequency, high dielectric loss below maximum operating temperature, use in volatile and toxic PbO, difficulty in preparing pure perovskite phases not involving pyrochlore phases [3,4].…”

Piezoelectric properties of Al 2 O 3 -doped Pb(Mn 1/3 Nb 2/3 )O 3 -PbZrO 3 -PbTiO 3 ceramics were investigated. The constituent phases, microstructure, electromechanical coupling factor, dielectric constant, piezoelectric charge and voltage constants were analyzed. Diffraction peaks for (002) and (200) planes were identified by X-ray diffractometer for all the specimens doped with Al 2 O 3 . The highest sintered density of 7.8 g/cm 3 was obtained for 0.2 wt% Al 2 O 3 -doped specimen. Grain size increased by doping Al 2 O 3 up to 0.3 wt%, and it decreased by more doping. Electromechanical coupling factor, dielectric constant, piezoelectric charge and voltage constants increased by doping Al 2 O 3 up to 0.2 wt%, and it decreased by more doping. This might result from the formation of oxygen vacancies due to defects in O 2− ion sites and the substitution of Al 3+ ions.
