Overview
Solid solution PbZr1-xTixO3 in composition range 0Researchers at the University of Maryland have come up with an invention pertaining to perovskite compounds of formula BI1-x(RE)xFeO3, where RE is one or more of La, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. The materials are at or near morphotropic phase boundary compositions which display antiferroelectric properties. The materials may possess electrostrictive characteristics.
The novel compounds are lead-free and are antiferroelectric at room temperature with simple perovskite-based structures. They display robust piezoelectric properties. They can be used in piezoelectric actuators, piezoelectric motors, pyroelectric detectors, pyroelectric imagers, ferroelectric memories, ferroelectric capacitors, dielectric capacitors, tunable microwave filters and circulators.
