N2 - The perovskite solid solution system (1-x)BiScO 3-(x)PbTiO 3 represents an Interesting new family of high-temperature piezoelectric materials. Compositions near the morphotropic phase boundary (x ∼ 0.64) have been reported to have high Curie temperatures (T c > 450°C) and good piezoelectric coefficients (d 33 ∼ 460 pC/N). In this work, manganese additions were used to improve the high-temperature electrical resistivity and RC time constant of compositions near the morphotropic phase boundary. The addition of manganese was found to shift T C to slightly lower temperatures (442°C and 456°C for x = 0.64 and x = 0.66, respectively). The piezoelectric activities of the modified materials were found to be reduced slightly due to the hardening effect of manganese; however, the temperature stability and resistivity of the modified materials were significantly enhanced. In this paper we present, for the first time, a complete set of materials constants, including the elastic (s ij, c ij), piezoelectric (d ij, e ij, g ij, h ij), dielectric ε ij, β ij), and electromechanical (k ij) coefficients and compare them to both unmodified 0.36BiScO 3-0.64PbTiO 3 and PZT5A ceramics.
