In this paper, the effect of gel-calcination on piezoelectric property in (1-x) BiScO_3-xPbTiO_3 with the composition of x=0.635 is investigated. According to previous work, the heating rate of 200℃/h and holding for 210min having been taken as the basic processing condition. The BSPT powders were obtained from the same sol solution but calcined at different temperatures, and then the powders were used to prepare BSPT ceramics. The result shows that for the bulk ceramics with higher relative density (higher than 95%), with the increasing calcining temperature of the gel (from 420℃ to 500℃), the piezoelectric coefficient d_(33) of ceramic specimens first increases to maximum of 636pC/N at 450℃, then shows a fluctuation. In this work how the powder activity and the grain size affect (which was leaded by powder particle size) piezoelectric properties of BSPT ceramics are discussed.
