摘要：

Producing of PLZT powders by original two-stage co-precipitation method from mixed solution of inorganic salts ZrOCl2.8H(2)O, TiCl4, La(NO3)(3)center dot 6H(2)O, Pb(NO3)(2), was carried out. The sequence of phases formed during PLZT synthesis has been studied by X-ray and DTA analysis. Ceramic samples were prepared by two-stage hot-pressing technology. Dielectric, ferroelectric and optical properties have been measured. Ceramic microstructures were studied by SEM with energy dispersive analytical capability (EDX). The fine-grained microstructure was quite uniform with the average grain size of 5-7 mu m, without internal or grain boundary porosity. The optical transmittance of ceramic plates (thickness of 0.3 mm) measured at wavelength of 630 nm reached 67-69%. (c) 2006 Elsevier Ltd. All rights reserved.
