Abstract

The PZT(KP12) powder was synthesized by sintering at $1250^{\circ}C$ for 2hrs and wet milling for 24 hrs. The PZT composite mixed with PVdF was fabricated into bulk, sheet, and plate type and the characteristics of three types were estimated. The bulk type which has PZT volume percent of 70 showed the best piezoelectric constant. Dielectric constant increased exponentially as an increase of PZT volume percent. The figure of merit of bulk and plate type was better than pure PZT over PZT volume percent of 50.
