Abstract

Lead zirconia titanate (PZT) is the most often used piezoelectric material in various electronic applications like energy harvesters, ultrasonic capacitors and motors. It is true that PZT has a lot of significant drawbacks due to its 60% lead content, despite its outstanding ferroelectric, dielectric and piezoelectric properties which influenced by PZT's morphotropic phase boundary. The recently found potassium sodium niobate (KNN) is one of the most promising candidates for a new lead-free piezoelectric material. For the purpose of providing a resource and shedding light on the future, this paper provides a summary of the historical development of different phase boundaries in KNN materials and provides some guidance on how to achieve piezoelectric activity on par with PZT through a thorough examination and critical analysis of relevant articles by providing insight and perspective of KNN, which consists of detailed evaluation of the design, construction of phase boundaries and engineering for applications.

铌酸钾钠无铅压电陶瓷:基于铌酸钾钠材料的相界工程研究进展
& lt; abstract>钛酸锆铅(PZT)是各种电子应用中最常用的压电材料,如能量采集器、超声波电容器和电机。诚然,尽管PZT具有优异的铁电、介电和压电性能,但由于其60%的铅含量,PZT具有许多显着的缺点。最近发现的铌酸钾钠(KNN)是一种最有前途的新型无铅压电材料之一。为了提供资源和照亮未来,本文总结了KNN材料中不同相界的历史发展,并通过提供KNN的见解和观点,通过对相关文章的彻底检查和批判性分析,为如何实现与PZT相当的压电活性提供了一些指导,其中包括详细的设计评估;相边界的构建与应用工程。</p>& lt; / abstract>
