摘要：

Dielectric and piezoelectric properties have been investigated in bismuth layer-structure compounds SrBi4Ti4O15 (SBT) and BaBi4Ti4O15 (BBT)-based solid solutions. Lanthanum-substituted and manganese-added SBT and BBT form solid-solutions for all levels of Ba substitution. The Curie temperature and coercive field strength decrease monotonously with the amount of Ba substitution. The mechanical quality factor, Qm, of the thickness-shear vibration mode also decreases. The value of elastic compliance increases with the amount of Ba substitution, but conversely its temperature dependency decreases.
