N2 - Modified BiScO3-PbTiO3 (BSPT) tetragonal single crystals were grown using high temperature solution method. The dielectric, piezoelectric and elastic properties of single domain BSPT crystals, after poling along [001] crystallographic direction, have been determined experimentally using the resonance method. The results showed that the BSPT tetragonal crystals possess good piezoelectric properties, with electromechanical coupling factor about 88% and piezoelectric coefficient over 400pC/N at room temperature. BSPT tetragonal crystals have high Curie temperature around 436°C and high coercive field ∼28 kV/cm, also, the crystal exhibited a very good temperature stability of the properties till 380°C. For comparison, the material constants of tetragonal Pb(Zn 1/3Nb2/3)O3-PbTiO3 (PZNT) single crystals were measured and listed in this paper.
