Creating High Temperature Ferroelectrics by Using Ternary Components with Limited SolubilityHigh temperature ferroelectrics are needed for actuator applications ranging from drilling on the surface of Venus to fuel modulation in jet engines. Machine learning in previous work has dramatically reduced search space and produced new candidates for experimentation. It is possible to create high temperature piezoelectrics by changing the end member of ternary systems. The starting point was near the morphotropic phas boundary between BiScO3(BS) and PbTiO3 (PT) (38%/62%). The third end member was suggested by machine learning to create a high Tc with limited solubility; BiCo0.88Fe0.12O3 (BCF).
