Abstract: Bismuth based ferroelectrics xBi(Sc0.5,Yb0.5)O3–(1-x)PbTiO3 (BYSPT) solid-solution systems had been anticipated to hold a high Curie temperature (Tc), meeting the conditions for using under high-temperature environment. In the current research, a solid state reaction processing route had been adopted to synthesize BYSPT based ceramics, and developed BYSPT crystals by a flux approach. The as-grown BYSPT perovskite crystals exhibit a Tc of about 570°C, based on measurements of dielectric and thermal properties.
