摘要
无铅压电陶瓷的研究与开发已引起世界各国的高度重视。本文综合分析了近20年无铅压电陶瓷发明专利约140篇,从发明专利角度评述了无铅压电陶瓷的研究与发展现状,简要介绍了目前受到广泛研究的BaTiO3(BT)基无铅压电陶瓷、Bi1/2Na1/2TiO3(BNT)基无铅压电陶瓷、铋层状结构无铅压电陶瓷及铌酸盐系无铅压电陶瓷,并侧重介绍这些无铅压电陶瓷的组分、性能和制备方法。从无铅压电陶瓷发明专利的进展可以看出,在过去20年中,为促进人类社会的可持续发展,无铅压电陶瓷得到了广泛的研究和开发,并取得重要进展。
In this paper, the patents, the number of which is nearly 140,of leadfree piezoelectric ceramics in the past twenty years are summarized and analyzed. BaTiO3based, Bi1/2Na1/2TiO3based,Bilayer structure and niobate leadfree piezoelectric ceramics, with the composition, properties, and the techniques for fabricating these ceramics, were briefly described. It was obvious that the leadfree piezoelectric ceramics were being widely developed in the past twenty years for the sustainable development of the human being society.
