Abstract

Crystallographic aspects of (1−x)Pb(Zr0.52 Ti0.48)03−xPb(Co1/3Nb2/3)O3 systems were investigated by X-ray diffraction method. System contains rhombohedral, tetragonal, and pseudocubic phases at room temperature.

Crystal symmetry was changed from 4-fold to 3-fold symmetry by substituting Pb(Co1/3 Nb2/3)O3;PCN,to Pb(Zr0.52 Ti0 48)O3;PZT. As the substituted PCN concentration was increased, an increase in a-axis direction and a decrease in c-axis in the perovskite structure occurred simultaneously, so that the crystal symmetry was changed in such a way. Such unit cell distortion was also influenced by sintering temperature. In the higher sintering temperatures, the lattice parameter change occurred in the lower concentration range of PCN.
