中文摘要:

      钛酸锶作为重要的、新兴的电子陶瓷材料，具有高的介电常数和高的折射常数，有显著的压电性能，是重要的铁电体，可作为介电材料和光电材料。随着钛酸锶电子陶瓷应用的日益广泛和对其性能要求的不断提高，其制备工艺已经越来越受到重视。为了制得质量更高的功能材料与器件，必须通过各种方法合成超细、高纯、无严重团聚、有特定形态的粉体及致密性强、耐高温的薄膜。综合叙述了钛酸锶电子陶瓷粉体及薄膜的制备方法，介绍了它们的优缺点，对各种方法进行了比较。

英文摘要:

      Because of its good dielectric,piezoelectric,electrooptic and ferroelectric properties,Strontium titanate(SrTiO_3)is widely used as an important electronceramics material.It can be used not only for the manufacture of multilayer ceramic capacitors,but also for thermistors and electrooptic components.Nowadays,with the extensive applications and the excellent properties of SrTiO_3,more and more researchers are paying their attention to its synthesis.In this article,the preparation methods of powders and thin films of strontium titanate are reviewed.
