摘要
纳米级的钛酸锶钡(BST)陶瓷材料在电子、微波器件、存储元件等现代科技领域有着重要的应用,是一类成分和性能可调节的新型无机功能材料。在介绍BST的传统制备方法基础上,主要介绍了近几年国外制备BST纳米粉体采用的几种新型高效方法,并简要介绍了国外纳米BST材料的结构、形貌表征、性能检测和应用现状,指出了国内在这一领域研究中的不足之处。
Nanosized barium strontium titanates （Bar Sr1-x O3, BST） powders are key building blocks in such scientific applications as electronic, microwave and read ＆ memory （RAM） devices because compositions of BST materials are tunable and therefore their properties are adaptable. Some traditional methods for synthesizing nano-scale BST are briefly included, whereas some novel as well as efficient productive avenues are intensively introduced in this review. Structural, morphological and property characterizations as well as applications of BST nanomaterials are reviewed, some shortcomings of domestic research in this field are also proposed.
