초록

In this paper, the compositional and sintering time dependences of dielectric, electrooptic properties for X/55/45([Ca$.$La$.$Nb]/Zr/Ti)CLN-PZT ceramics, where X is ranged from 3.0 to 11.0 mol %, have been investigated. As CLN mol% is increased, density, curie-temperature and dielectric constant are decreased, and also grain size and transmittance are increased, With the increment of CLN mol %. longitudinal mode electromechanical coupling coefficient is decreased and P-E hysterisis loop became slim-loop slowly. The crystal structure of CLN-PZt ceramics is changed from rhombohedral to tetragonal and pseudo-cubic according to the increment of CLN mol%.
