| Abstract: | With the development of economy and the enhancement of the public environmental awareness,the research and development of lead-free ceramics was more and more brought to the forefront.Bi0.5Na0.5TiO3(abbr.BNT)-based piezoelectric ceramics were extensively studied because of their excellent ferroelectric properties.The recent progress of BNT-based lead-free piezoelectric ceramics were reviewed in this paper.Grain oriented growth technique is considered to be an important way to improve the piezoelectric properties of BNT ceramics.In this paper,textured BNT lead-free ceramics were synthesized using solvothermal method. |
