钛酸钡(BaTiO3)和铌酸钾钠(K0.5Na0.5NbO3)压电陶瓷因具有环境友好、电学性能良好、居里温度较好等优势而成为国际高新技术材料研究的前沿热点,有望替代部分铅基压电陶瓷应用于国防、航空航天、通信等领域的电子器件中.本文综述了BaTiO3和K0.5Na0.5NbO3压电陶瓷材料的最新研究进展,从构造相界调控压电性能、BaTiO3基压电陶瓷的材料体系设计、K0.5Na0.5NbO3基压电陶瓷的热稳定性及改善、压电陶瓷的新型成型及烧结工艺等方面进行客观分析和总结,并展望了两种材料的未来发展趋势,为开发高性能无铅压电陶瓷提供参考.
Research Progress of Barium Titanate and Potassium Sodium Niobate Lead-Free Piezoelectric Ceramics
Barium titanate(BaTiO3)and potassium sodium niobate(K0.5Na0.5NbO3)piezoelectric ceramics have become the forefront of international high-tech materials research due to their environmental friendliness,excellent electrical properties and proper curie temperature,and were expected to replace some lead-based piezoelectric ceramics in electronic devices in the fields of national defense,aerospace and communications,etc.In this paper,the latest research progress of BaTiO3 and K0.5 Na0.5 NbO3 piezoelectric ceramic materials was reviewed,the aspect of constructing phase boundary to regulate the piezoelectric performance,designing the material system of BaTiO3-based piezoelectric ceramics,the thermal stability and improvement of K0.5 Na0.5 NbO3-based piezoelectric ceramics and the new molding and sintering process of piezoelectric ceramics were analyzed and summarized objectively.Finally,future development trend of the two kinds of materials was discussed,and a reference for the development of high-performance lead-free piezoelectric ceramics was provided.
