Polycrystalline samples of (Pb0.93R0.07)(Zr0.60Ti0.40)(0.9825)O-3 (R = Y La
Nd, Sm, Gd, Dy, Eu, Pr, Er and Yb) have been prepared by sol-gel technique
. Structural and microstructural parameters Rave been determined using XRD
and SEM techniques. Studies of dielectric constant as a function of tempera
ture and frequency suggest that the compounds have diffuse phase transition
of second order. From the studies of polarisation, and piezoelectric prope
rties, some interesting results have been obtained.
