N2 - The effect of domain structures on the piezoelectric properties of three typical lead-free piezoelectric ceramics, (1-x)Bi0.5Na 0.5TiO3-xBaTiO3, (Na0.52K 0.48-x)(Nb0.95-xTa0.05)O3- xLiSbO3 and 0.5Ba(Zr0.2Ti0.8)O 3-0.5(Ba0.7Ca0.3)TiO3, have been studied by transmission electron microscopy. By adding BaTiO3 in single phase Bi0.5Na0.5TiO3, domain structure changed from irregular domains into submicron lamellar domains and polar nano-regions. While in the later two system, regular submicron domains with nanodomains inside formed, which is an important feature of these two systems. It is suggested that the changes in domain structures in these systems have a dominant effect in the enhancement of the piezoelectric properties, comparing with single phase Bi0.5Na0.5TiO3, Na 0.5K0.5NbO3 and BaTiO3. © 2014 Elsevier Ltd and Techna Group S.r.l.
