| Abstract: | For environmental protection reasons, lead-free piezoelectric ceramics have attracted considerable attention recently. In this paper, the recent researches and development of Bi_(0.5)Na_(0.5)TiO_3-based, K1-xNaxNbO_3-based, Bi-layer structure, tungsten bronze structure and BaTiO_3-based lead-free piezoelectric ceramics are summarized and reviewed in detail. This paper analysizes and appraises the ceramic system, modification methods, process technology and piezoelectric ferroelectric properties. The phase transition and temperature stability of Bi_(0.5)Na_(0.5)TiO_3- and K1-xNaxNbO_3-based lead-free ceramics are emphatically discussed. The future work on lead-free piezoelectric ceramics is also suggested. |
