Lead - free piezoelectric ceramics have been attracting great attention worldwide from the viewpoint of environmental protection. In this paper, the lead - free piezoelectric ceramics so far are summarized and the recent progresses of these ceramics are generally reviewed. It is pointed out that BaTiO3 - based, Bi0.5Na0.5TiO3 - based, Nb - system and Bi - layer structured lead - free piezoelectric ceramics are being widely studied internationally.
