Novel perovskite-type ferroelectrics with high curie temperature and piezoresponse

Through data-mining of material genome approach, perovskite-type BiFeO 3 -Bi(Zn 1/2 Ti 1/2 )O 3 -PbTiO 3 and BiFeO 3 -Bi(Zn 1/2 Ti 1/2 )O 3 -BaTiO 3 ternary solid solution were designed theoretically and demonstrated experimentally to be promising novel high temperature ferroelectric piezoceramic materials. Like the PZT system, they are potential alternatives of PbNb 2 O 6 and Bi 4 Ti 3 O 12 -based piezoceramics for future piezotronic applications operating in the hot environments.
