Influence of Structural Phase Transitions on the Mechanical Behavior of Lead-Free Potassium Sodium Niobate Piezoceramics

结构相变对无铅铌酸钾钠压电陶瓷力学行为的影响

基本信息

项目摘要

A growing critical environmental issue exists related to the increasing use of toxic lead-based piezoelectric ceramics for various sensor and actuator applications. There have been substantial scientific and industrial efforts towards the development of lead-free alternatives, which have led to the identification of various potential material systems. Polycrystalline (KxNa1- x)NbO3 (KNN) remains one of the most promising candidates, with a high Curie point, stable electromechanical response over a wide usable temperature range, high acoustic vibration velocities, and low density. Despite the numerous advancements in tailoring the electromechanical properties, there has been very little work on understanding the mechanical response, in particular the fracture behavior, which is crucial for reliable commercial implementation. During operation piezoelectric ceramics are often exposed to high operating temperatures and large compressive stress, used to reduce cracking. Therefore, the aim of this project is to use combined and complementary experimental techniques and expertise in Germany and China to characterize the temperature-dependent mechanical properties and in situ stress-dependent crystal structure of KNN with various advanced novel measurement techniques.
一个日益严重的环境问题,存在与有毒的铅基压电陶瓷的各种传感器和致动器的应用越来越多的使用。科学界和工业界为开发无铅替代品做出了大量努力,从而确定了各种潜在的材料系统。多晶(KxNa 1- x)NbO 3(KNN)仍然是最有前途的候选者之一,具有高居里点、在宽的可用温度范围内稳定的机电响应、高的声振动速度和低密度。尽管在定制机电性能方面取得了许多进展,但在理解机械响应方面的工作很少,特别是断裂行为,这对于可靠的商业实施至关重要。在操作期间,压电陶瓷经常暴露于高操作温度和大的压缩应力,用于减少开裂。因此,该项目的目的是利用德国和中国的组合和互补实验技术和专业知识,通过各种先进的新型测量技术来表征KNN的温度相关力学性能和原位应力相关晶体结构。
