Abstract: Lead-free piezoceramics with the composition 0.7(Bi1-xNdx)FeO3-0.3BaTiO3+0.1 wt% MnO2 (BNxF-BT) were prepared using a conventional solid state route. X-ray diffraction and temperature dependent permittivity measurements indicated a transition from a composition lying at a morphotropic phase… read more here.

Abstract: Abstract An approach of composition modification in (Bi,Na,Ba,Sr)(Ti,Nb,Zr)O3 (BNSTNZ)–modified 0.65Bi1.05FeO3–0.35BaTiO3 (BF35BT) piezoelectric materials was investigated. Introducing BNSTNZ into BF35BT ceramics led from the normal-ferroelectric to relaxor-ferroelectric- phase. At the optimum composition, large dynamic piezoelectric coefficient… read more here.
