Abstract
We know that the piezoelectric constant d, the dielectric constant, and the electric-mechanical coupling coefficient affect the output for piezoelectric ceramics used in ultrasonic welders. Therefore, in this study, the characteristics of ceramics according to the changes of additives to the components of PZT-PMN-PZW were examined. When the addition amount of $MnO_2$ was 2 wt%, the most excellent properties were shown, which suggested the applicability as a material for fusion welding.
