摘要
近年来,织构化工艺作为一种提高无铅陶瓷压电性能的有效方法,在国内外得到了广泛地研究和关注.本文综述了几种常用的织构化工艺,包括热处理技术、非等轴粒子取向固化技术、模板晶粒生长技术、反应模板晶粒生长技术和多层晶粒生长法的发展与应用,并详细讨论了每一种工艺对陶瓷微结构和织构化生长机制的影响.
Recently, texture technique, which is an effective method to improve the piezoelectric properties of Lead-free ceramics, has been widely investigated and attracted much attention. In this paper, several texture techniques, such as hot processing, oriented consolidation of anisometric particles, templated grain growth, reactive templated grain growth and multi-layer grain growth techniques, and along with their development and applications to Lead-free piezoceramics, are reviewed. The influences of texture processing on microstructure and grain growth mechanisms of textured ceramics are discussed in detail.
