Preparation and Characterization of (1-x)BiScO3-xPbTiO3 Ceramics by Two-step Sintering

摘要：

　　High-performance fine-grain (1-x)BiScO3-xPbTiO3 ceramics were prepared by two-step sintering method.Influences of sintering temperature,holding time,and composition on the microstructure and properties were discussed.The BSPT ceramics obtained via two-step sintering reaches density higher than 95% at a low temperature of 800℃ without any sintering aid,and the grain size of the ceramics is also effectively controlled.Excellent piezoelectric properties between the composition of x=0.63 and x=0.64 reveals a probable MPB in this range,suggesting a potential approach to pursue high performance BSPT ceramics.
