Abstract
Abstract Ferroelectric ceramics in specific composition of 0.95Pb(Zr x Ti 1− x )O 3 –0.05Pb(Mn 1/3 Nb 2/3 )O 3 or PZT–PMnN (with x =0.46, 0.48, 0.50, 0.52, and 0.54) have been investigated in order to identify the morphotropic phase boundary (MPB) composition. The effects of Zr/Ti ratio on phase formation, dielectric and ferroelectric properties of the specimens have also been investigated and discussed. X-ray diffraction patterns indicate that the MPB of the tetragonal and rhombohedral phase lies in x =0.52. The crystal structure of PZT–PMnN appeared to change gradually from tetragonal to rhombohedral phase with increasing Zr content. The dielectric and ferroelectric properties measurements also show a maximum value ( e r , tan δ and P r ) at Zr/Ti=52/48, while the transition temperature decreases with increasing Zr content.
