Abstract

Transparent relaxor ferroelectric ceramics of (1-x)Pb(Mg1/3Nb2/3)03-(x)PbTiO3 and Pb(Scl/2Tal/2)03 have been prepared by low temperature uniaxial hot-pressing. The ceramics are highly dense (> 99.5 % theor.) and transmit throughout the visible. The addition of excess PbO and La2O3 and post-pressing heat treatment are found to enhance transparency. The ceramics have been characterized for phase purity, development of microstructure, dielectric behavior and optical transmission in order to determine optimum conditions.
