Abstract:
As one of lead-free piezoelectric and ferroelectric ceramics, structure and electrical properties of (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics have been widely studied. Effects of point defects in (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics, are summarized in this work. The contents include introduction of crystallite structure and electrical properties of (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics, point defects in (Na0.5Bi0.5)0.94Ba0.06TiO3, reported methods for characterizing point defects, effects of ion nonstoichiometry, ion doping, technology parameters on structure and electrical properties of (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics. Ion nonstoichiometry, ion doping, and technology parameters can cause changes in type and concentration of point defects, which will affect structure and electrical properties of (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics. Based on the overview about point defect effects of structrue and electrical properties of (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics, it is hoped to provide reference for the design and control structrue and electrical properties of functional ceramics via the point defect effects.
