  • In this study, $0.085Ba(La_{1/2}Nb_{1/2})O_3-0.915Pb(Zr_yTi_{1-y})O_3$(y=0.45, 0.50, 0.55, 0.60, 0.65[mol]) transparent electrooptic ceramics were fabricated by two-stage sintering method. Increasing the $PbZrO_3$ contents, dielectric constant was increased and Curie temperature was decreased. In the composition of 0.55[mol] $PbZrO_3$, electromechanical coupling factor was 0.43. From the results of ferroelectric hysteresis loop and transmitted light intensity with electric field, the compositions of 0.65, 0.60, 0.55[mol] $PbZrO_3$ was applicable to electroopticmemory device and the compositions of 0.50, 0.45[mol] $PbZrO_3$ was applicable to linear electrooptic device.
