Abstract
The Sm-modified lead titanate ceramics with a composition of (Pb 0.85Sm0.1)-(Ti0.98Mn0.02)O 3 piezoceramics doped with SiO2 were prepared by conventional mixed-oxide method using sintering temperature at 1100°C. Microstructural and compositional analyses of the PbTiO3-based ceramics have been carried out using XRD and SEM. The effects of dopants on the sintering temperature and piezoelectric properties of the ceramics have been investigated. We successfully showed that these additives were helpful in lowering of the sintering temperature and still keep high thickness electromechanical coupling coefficient, kt, and small planar electromechanical coupling coefficient, kp. Surface acoustic wave (SAW) devices were fabricated and the properties, including phase velocity and temperature coefficient of frequency (TCF), were measured.
