The effect of adding Al_2O_3 to the PZT-PMN solid solution material for use for ceramic resonator was investigated. It has been found that when the amount of Al_2O_3 added to PZT-PMN is 0.3 wt% or below, it exists inside the crystal lattice as Al~(3+) ion and increases the stability of oscillation frequency over application of heat (heat resistance). It has been found that when more than 0.3 wt% of Al_2O_3 is added, the Al~(3+) ion that remained undoped will exist at grain boundary as secondary phase, and increase the strength.
