Abstract

The Sm-modified lead titanate ceramics with a composition of (Pb0.88-xSrxSm0.08)(Ti0.98Mn0.0 2)O3; x = 0.05-0.25 were prepared by conventional mixed-oxide method. Surface acoustic wave (SAW) properties, including phase velocity, electromechanical coupling coefficient and temperature coefficient of frequency, were measured. The experiments successfully showed that Sr additive is helpful to obtain higher phase velocity and high electromechanical coupling coefficient. The SAW properties of our samples (Vp,k2) are better than some commercially-made PZT and PT samples.
