Hot-pressed (Pb, RA(ZR, Ti, RB)O3 ferroelectric ceramics for electro-optic applications

This paper reports the effects of new substitutional ions on achieving optically transparent hot-pressed lead zirconate titanate ceramics. The effects of both single ion substitution and simultaneous substitution of different ions at A and B sites were examined. In single ion substitution, the experimental results were negative. It was found that simultaneous substitution of two kinds of ions was very effective in producing transparent hot-pressed PZT ceramics. New transparent ferroelectric ceramics suitable for electro-optic applications have been prepared by simultaneous substitution of mono- and penta-valent ions or two trivalent ions, such as Na1+ and Nb5+, K1+ and Ta5+, and Sm3+ and In3 +.
