Abstract
Abstract The Pb(Mg 1/3 Nb 2/3 )O 3 –Pb(Ti,Zr)O 3 system near morphotropic phase boundary (MPB) can be expected to provide a high piezoelectric charge coefficient and electromechanical coupling coefficient. Therefore, it has been used as an excellent candidate for piezoelectric applications, including energy harvester applications. In this study, electric field-induced phase transition in (1− x )(PbMgNbO 3 –PbZrTiO 3 )– x (BaTiO 3 ) ceramics in a relatively low field of 40 kV/cm will be discussed. XRD analysis showed tetragonal and rhombohedral perovskite structure of PbMgNbO 3 –PbZrTiO 3 with BaTiO 3 , indicated that phase transition was occurred with increasing BaTiO 3 , component. Measurement of room temperature dielectric constant indicated a gradual increase with increasing BaTiO 3 content. The results show that the addition of BaTiO 3 is very effective in improving the dielectric and electric properties of Pb(Mg 1/3 Nb 2/3 )O 3 –Pb(Ti,Zr)O 3 system.
