Abstract

It is well known that no single phase Pb(Mg_{1 3}Nb_{2 3})O₃ could be prepared by the conventional ceramic route due to the formation of pyrochlore. A new thermal shock method has been developed for the synthesis of the stoichiometric ultra-fine powder (ø=70-250nm) of Pb(Mg_{1 3}Nb_{2 3})O₃ from metal-citrate gel. The optimum synthetic temperature and reaction temperature have been determined as approximately 900°C and 40 minutes, respectively.
