复合氧化物电子功能陶瓷的现状与展望

Recent Status and Prospects of Functional Composite oxide Electroceramics

本文阐述了复会氧化物电子功能陶瓷的概念、分类、设计原则、复会机理以及典型应用，并对复合氧化物电子功能陶瓷的发展方向作一简单的介绍。复合氧化物电子功能陶瓷主要分为固溶型、机械混合型、晶界偏析型、包覆型、两相反应型等。其复合机制主要有加和性、乘积性、多色渗滤等，未来复合氧化物电子功能陶瓷的发展方向主要有：１．纳米级复合氧化物电子功能陶瓷材料的设计与制造；２．多功能复合氧化物电子功能陶瓷材料的设计与制造；３．无污染、可再生的复合氧化物电子功能陶瓷材料的开发与研究。

The conception,classification,designprinciple,combination mechanism and the developing trend of the functional composite oxide electro-ceramics(FCOE)have been introduced in this paper. The functional composite oxide electroceramicscan be specified into solid solution,rnechanical mixture grain boundary segeration type,grain-in-graintype and reaction type,etc. And the compositemechanism consists of sum effect,product effectand polychromatic percolation. The prospects of theFCOE are mainly as follows 1.The design andmanufacture of the nanometer scale FCOE:2.Thedesign and manufacture of the multifunctional com-posite oxMe electroceramics;3.The exploitation ofthe nopollution and reproducible FCOE.
