Electro-optical properties of transparent PLZT ceramics are substantially dependent on their microstructure. To obtain a high degree of optical quality it is necessary to produce PLZT free of any second phase including porosity. Critical grain size for optical transparency and dielectric properties must also to be taken into account. A two stage PLZT production process yielding samples of good electro-optical (EO) quality was developed. The method includes sintering in oxygen in the presence of PbO-rich liquid phase and hot-pressing in an air atmosphere. The influence of liquid phase sintering and hot-pressing conditions on the PLZT microstructure are discussed. Conclusions are drawn regarding control of the final grain size in PLZT.
