In this study, the piezoelectric ceramics PZT powders were synthesized by Wet-Dry combination method. And the flexible 1-3-0 type composites were favricated with piezoceramic PZT and Eccogel polymer matrix embedded 3rd phase. Dielectric constant of 1-3-0 type composites was lower than that of single phase PZT ceramics. Thickness mode coupling factor $k_t$ which was comparable with single phase PZT ceramics, and Mechanical Quality factor $Q_m$ were about 0.65 and 6 respectively. These composites are considered as a good candidates for broad-band type transducer applications. The acoustic impedance for 1-3-0 type composites was lower than that of single phase PZT ceramics. Therefore, these composites would be better used for hydrophone applications.
