| Abstract: | Niobate-based lead-free piezoelectric ceramics, especially niobate with tungsten bronze structure, have received great attention as new piezoelectric materials from the viewpoint of environmental protection. In this paper, the patents of niobate-based lead-free piezoelectric ceramics in the past twenty years were summarized and reviewed. The future developments of niobate-based lead-free piezoelectric ceramics, especially for the substitution, composition and theoretical studies of NaNbO_3,Sr_2NaNb_5O_(15) and related tungsten bronze niobate, were suggested. |
