Hydrothermal synthesis of lead titanate and lead zirconate titanate electroceramic particles
Özet
Hydrothermal synthesis of two lead-based perovskite powder systems, lead titanate and lead zirconate titanate, was investigated. Phase-pure perovskite lead titanate and lead zirconate titanate with various morphologies have been synthesized by hydrothermal methods at 150degrees and 175degreesC, respectively. Solution pH should be greater than 14 to obtain the phase-pure perovskite phases in a reasonable time. In addition, the KOH concentration and the stirring rate significantly influence particle morphology of the hydrothermally derived PT and PZT. Therefore, these parameters can be used to tailor particle size and morphology.
