Abstract
Lead magnesium niobate-lead titanate (PMN-PT) ceramic fibres with the nominal composition of 0.65Pb(Mg1/3Nb2/3)O3-0.35PbTiO3were synthesised using PMN-PT single crystal powder and poly(acrylic acid). The fibres were extruded directly by pressing the mixture through a spinneret. The fibres were well crystallised after sintering at 1250°C and the final diameter was around 300 μm. The microstructural properties of the fibres were investigated using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The electrical characteristics of the fibre were determined by measuring the hysteresis D-E loop, relative permittivity and impedance spectrum. The measured results showed that this method can be used to fabricate PMN-PT fibres with good performance.
