Abstract
Abstract Microstructures and properties of semi-conductive Pb 0.6 Sr 0.4 TiO 3 ceramics fabricated from PbTiO 3 -coated SrTiO 3 powders were investigated using X-ray and electron diffraction, transmission electron microscopy and energy dispersive spectroscopy. PbTiO 3 -coated SrTiO 3 powders were prepared for simulating the core-shell structure in Pb 0.6 Sr 0.4 TiO 3 ceramics, which were sintered by microwave, rapid thermal and conventional sintering processes. After TEM investigations and EDS analyses, it is found that the microwave-sintered specimens preserve the starting core-shell structure more effectively than the conventional and rapid thermal sintered specimens. According to our core-shell model, the microwave-sintered specimens show single T c and the conventional, rapid thermal sintered specimens exhibit double T c behavior, as verified by the resistivity–temperature ( ρ – T ) properties. Our interpretation implies that the core-shell structure may be the primary factor affecting the ρ – T properties.
