A new ferroelectric solid solution of (0.90-x)BiScO3-xPbTiO3-0.10Pb(Mn1/3Ta2/3)O3 (BS-PT-PMT, x = 0.54-0.70) has been synthesized in the form of ceramics by solid-state sintering and characterized by means of X-ray diffraction, ferroelectric and piezoelectric measurement. All ceramics with different compositions crystallize in the pure perovskite phase. With increasing PT content, a morphotropic phase boundary (MPB) is established at x ≈ 0.58 by X-ray analysis. The dielectric, ferroelectric, and piezoelectric characterization of the compositions near MPB were discussed.
