Preparation of PZT Material with Different Zi/Ti Ratio by Sol-Gel Method
View through CrossRef
Lead zirconate titanate powders (PZT) with different Zi/Ti values 52/48, 53/47, 54/46 and 55/45 were prepared by sol-gel technique. The sol was prepared by mixing stable solutions of Zr-nitrate, Pb-acetate and Ti (OC4H9)4 precursors. The decomposition of precursors above 773 K, 923 K and 1073 K for Zi/Ti value equls to 52/48; 53/47 and 54/46; 55/45 leads to the formation of pure perovskite phase, respectively. X-ray diffraction analysis was carried out to confirm the phase formation of PZT. The relationship of synthesis temperature and Zi/Ti ratio value is disscused and it is found that higher synthesis temperature is needed to prepare pure PZT with increasing Zi/Ti ratio.
