Dielectric and Piezoelectric Properties of Ceramics

Piezoelectric and ferroelectric properties are know to be closely associated
with proximity to phase transitions, but attempts to identify general rules
for identifying and exploiting such phase transitions have had limited success.
By learning from a wide range of literature reports, we hope to identify
relationships and descriptors that are more predictive than existing
design rules based on things like crystal chemistry (such as tolerance
factors) or empirical mixing rules. Initial efforts have focused on
classic studies targeting development of high-temperature perovskite
piezoelectrics. designed properties, in such a way as to greatly
reduce the time and cost for developments of NiTiHf shape memory alloys.
