Powder of sodium doped polycrystalline samples of PLZT with composition Pb-0.98(La1-x/3Nax)(0.02)(Zr-0.53 Ti-0.47)(0.9950) .O-3 (PLNZT) with x = 0.5 was systematically prepared using spray drying technique. Rhombohedral phase of PLNZT compound has been confirmed after being calcined at 800 degreesC. IDTA-TGA and XRD studies were used to characterize the compound synthesized. SEM was used for micro-structural evaluation. The dielectric constant (epsilon) and loss tangent (tan delta) of the compound were studied at different temperatures at 10 kHz frequency, which suggests that the compound undergoes a ferro-electric phase transition of diffuse type.
