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