Ternary PZT-PNM* ceramics is prepared by low vacuum atmosphere(5×10-2bar) sintering technique to improve the microstructure, density, polished surface smoothness, as well as the piezoelectric properties. The grain growth has been restrained by doping small amount of CeO2. At the same time. The density up to 7.97g/cm3 and grain size less than 2um have also been obtained. The size of pits on the polished surface is less than 0.5um. It is suitable for manufacturing SAW devices in medium high frequency of 10 to 40 MHz. |
