Characterisation of Nanocrystalline PZT Synthesised via a Hydrothermal Method

摘要

This paper describes the progress made toward characterising lead zirconate titanate (PZT) synthesised via a novel hydrothermal method. Low temperatures ( ≤ 200℃) and high mineraliser (potassium hydroxide) concentrations were used to produce single-phase, perovskite PZT in a bomb-type reactor. Full phase purity was attained after just 30 minutes of processing at 160℃. The particles had a wide size distribution, from nanoscale agglomerates with irregular morphology, up to micron-sized cubes. It is believed that the differences in morphology can be attributed to two distinct formation stages.
