摘要
试验以ＰＭＮ 基弛豫铁电体为基础，通过掺杂和优化工艺，研制出性能优异的电致伸缩材料（１ －ｙ）［（１ － ｘ）ＰＭＮ－ ｘＰＴ］－ ｙＷＯ３ ，分析讨论了掺杂改性对材料性能的影响。进一步阐明材料宏观性能与微观结构之间的关系。
Through improving preparation process and modifying the composition, the excellent PMN-based electristrictive ceramics with a formula of (1- y )[(1- x )PMN- x PT]- y WO 3 have been prepared. The effects of additives on the properties and the relationship between the electristrictive properties and microstructure of the ceramics were discussed in the present work.
