Abstract
Nano sized $(Pb_{0.5}Ca_{0.5})(Fe_{0.5}Nb_{0.5})O_3$ (PCFN) powders with the stoichiometric composition and the uniform size distribution were successfully synthesized by the metal-citrate process through the calcination of the polymeric precursor which consisted of the metal ions and the organic network. The crystallization of the initial amorphous powders began at $400{\circ}$ and completed at $700{\circ}$. The pyrochlore phase was detected caused by the dissociation of PbO above $900{\circ}$. Single phase perovskite PCFN powders with 40 nm size and uniform shape were obtained through the calcination at $700{\circ}$.
