Researches on the Lead-free Piezoelectric Ceramics and Their Applications

Today, the researches of lead-free piezoelectric ceramics and their applications are extremely important as a result of implementing the strategy which the society of the world can sustainablly develop, and strengthening to the consciousness of environmental protection. The recent progress of lead-free piezoelectric ceramics and the present conditions of the applications of these materials are summarized and analyzed on the basis of the development of the domestic and overseas involved in these ceramics, including the researches of professor Xiao Dingquan and his group in recent years. The properties of the five systems such as BaTiO 3, Bi 1/2Na 1/2TiO 3-based, alkaline niobate-based, tungsten-bronze structure, and bismuth-layer structure lead-free piezoelectric ceramics, and the applications and the prospects of Bi 1/2Na 1/2TiO 3-based lead-free piezoelectric ceramics applied to filters are reviewed.
