Abstract :
Ferroelectric and piezoelectric properties of barium doped PZT are investigated for various concentrations of barium. Planar coupling coefficient kp of 0.5 was obtained. d33 values are in the range of 300-500 pC/N. The results obtained show that the PZTs developed by us can be used for underwater hydrophones
