A perovskite lead zirconate was synthesized, using lead glycolate and sodium tris (glycozirconate) as the starting precursors, by the sol-gel process. The obtained molar ratio Pb : Zr of PbZrO 3 was 0.9805 : 1. The TGA-DSC characterizations indicated that the percentage of ceramic yield was 56.4, close to the calculated chemical composition of 59.6. The exothermic peak occurred at 245.7 • C, close to the theoretical Curie temperature of 230 • C. The pyrolysis of PbZrO 3 of the perovskite phase was investigated in terms of calcination temperature and time. The structure obtained was the orthorhombic form when calcined at low temperature at 300 • C for 1 h; it transformed to the monoclinic and cubic forms of the perovskite phase at higher temperatures above the Curie temperature as verified by X-ray data. The lead zirconate synthesized and calcined at 300 • C for 1 h has the highest dielectric constant, the highest electrical conductivity and the dielectric loss tangent of 2267, 3.058 × 10 −4 ( m) −1 and 2.484 at 1000 Hz, respectively. The lead zirconate powder produced has potential applications as materials used in microelectronics and microelectromechanical systems.

“…With the tetragonal structure of the perovskite phase, we may expect the ferroeletric and the piezoelectric properties. [16] At higher calcination temperatures, above www.interscience.wiley.com/journal/aoc the Curie temperature of Pb(Zr 0.5 Ti 0.5 )O 3 of 400 • C, we may expect both the dielectric constant and the electrical conductivity to decrease with increasing calcination temperature since the structures become more of the cubic form, which is accompanied by paraelectricity.…”

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.
