| Abstract: | In recent years,with the need of environmental protection and reusing,Ba_(0.5)Na_(0.5)TiO_3(BNT)-based lead-free piezoelectric ceramics,which is considered to be aprominent candidate for environment conscious piezoelectric ferroelectric ceramics,have became one of materials being researched by the developed countries.In this paper,according to the recent report of BNT-based,the piezoelectric mechanism and the process of phase transformation are discussed.It is pointed out that the method of preparation,modification and recent application of BNT piezoelectric ceramics are being widely studied internationally with the most interest.Finally,the future prospect of BNT-based is advanced. |
