Abstract
- Dense (1-y)BiFe1-x(Mg0.5Ti0.5)xO3 - yBaTiO3 (BFMT-BT, y = 0.29, x = 0-0.12) ceramics with a pseudocubic perovskite crystal structure exhibit remarkably high-temperature stable piezoelectric properties. In particular, x = 0.03 BFMT-BT ceramics, with a Curie temperature, Tc, of ∼425 °C, show a stable piezoelectric coefficient, d33, of ∼155 pC/N up to a depolarization temperature, Td, of ∼400 °C. This Td is higher than Tc for Pb(Zr,Ti)O3, therefore suggesting BFMT-BT ceramics to be promising high-temperature Pb-free piezoelectric materials. [ABSTRACT FROM AUTHOR]
