Abstract

Lead magnesium niobate-lead titanate (PMN-PT) ceramic fibres with a nominal composition of 0.65Pb(Mg1/3Nb2/3)O3-0. 35PbriO3have been fabricated by a modified sol-gel technique. The ceramic fibres with 100 μm diameter were well-crystallized after being calcined at 850°C and sintered at 1200°C. After being poled, the electromechanical coefficient of the single PMN-PT ceramic fibre is 0.5. The relative permittivity of the single ceramic fibre was higher than that of a ceramic disc while their hysteresis loops are comparable. The characterization of the ceramic fibres reveals that the modified sol-gel method can be used to fabricate PMN-PT ceramic fibres with good piezoelectric and ferroelectric properties.
