Abstract
Nanocrystalline powders of La-modified lead zirconate titanate (PLZT: 7/60/40) solid solution have been synthesized via mechanochemical processing. No excess PbO was used in the starting composition. Scanning and transmission electron microscopy revealed the formation of powders on the nano-scale. Sintering the powders resulted in dense compacts, at reduced sintering temperatures. Well-saturated ferroelectric hysteresis loops with a Pr on the order of ∼48 µC cm−2 and coercive fields of ∼7 kV cm−1 were recorded on the samples. Strain levels up to > 0.25% with limited hysteresis (<0.05% in the low field region) indicate the tremendous potential of these ceramics for high-performance actuators, especially in cases where a high degree of positioning accuracy is required.
