PLZT ceramics prepared from conventional and microwave hydrothermal powders

Abstract

Phase pure PLZT (3/52/48) powders were synthesized at a low temperature of 138°C by both conventional and microwave hydrothermal (MH) methods without using excess lead content. PLZT ceramics fabricated from the above powders resulted in 96% of theoretical density upon sintering. Properties such as crystallinity. morphology of the as prepared MH powders and densification and miciostructure of the sintered pellets were studied. These properties of MH samples were compared with the properties of those prepared by conventional hydro-thermal method (CH).
