In this study, a comparative structural analysis of bismuth doped PZT nanoceramics (i.e. Pb0.98 BI0.02 (Zr0.52 TI0.48)0.98 O3) prepared by chemical co-precipitation and sol-gel methods has been made. Perovskite PZT phase in the compound prepared by sol-gel method can be seen ta the temperature as low as 250°C whereas the evolution of PZT phase along with small amount of pyrochlore phase take place only after 400°C temperature in the samples prepared by co-precipitation method. The X-Ray diffractogram of pellets sintered at 1100°C also confirms that bismuth doping does not affect the crystal structure of the compounds and a tetragonal unit cell structure was formed in both of the cases.
