Abstract
Potassium-modified PLZT [Pb-0.92(La-1-(z)0.08)(Zr0.60Ti0.40)(0.98+0.04z)O-3
(z = 0.0, 0.1, 0.3, 0.5, 0.7)] ceramics were synthesised using sol-gel tec
hnique. Preliminary structural and microstructural parameters were determin
ed using XRD, SEM and TEM techniques. Detailed studies of dielectric proper
ties at 10 kHz in a wide temperature range suggest that the compounds have
diffuse phase transition of second order. Studies of spontaneous polarisati
on, pyroelectric and piezoelectric properties yielded data for devices. (C)
