Abstract
The long-size electro-optic ceramics of (Pb,La)(Zr,Ti)O3 were fabricated by combination of partial-coprecipitation and doctor-blade method. The PLZT powder with sub-micron of particle size and excellent dispersed was prepard by using (Zr,Ti)O2 solid solution powdewr which was synthesised according to coprecipitation method, PbO and La2O3 powders. The long-sized PLZT ceramics with 30 cm of length and 2 mm of thickness molded by doctor-blade method and then ordinary sintered.
