Hydrothermal synthesis and characteristics of lanthanumdoped Pb(Zr₀.₆₅Ti ₀.₃₅)O₃ ceramics
Main Article Content
Abstract
Lanthanum-doped lead zirconate titanate (PLZT) powders were synthesized using the
hydrothermal method. The influence of pH, reaction temperature and time, lanthanum concentration on the formation and characteristics of PLZT were investigated. Obtained powders were investigated using X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) techniques and a dielectric analyzer. The results showed that Pb1-xLax(Zr0.65Ti0.35)O3 with x= 0.0 – 0.1 were well formed under conditions: pH≥13, reaction time of 12hrs, reaction temperature of 180oC. Dielectric constant of PLZT is higher than PZT. The grain size of the PLZT is found to be 1–3.5 µm.
