摘要:

介绍了溶胶－凝胶法的原料、原理以及无机盐和金属醇盐的水解特点以及溶胶－凝胶方法的最新进展，存在的问题，并结合作者自己的研究工作，以二氧化锡为例，介绍了溶胶－凝胶法的工艺流程，最后对溶胶－凝胶法的未来发展进行了展望。

Abstract:

The Sol-Gel (S-G) method is a moderate temperature process for prepa ring nanomaterials. In this paper, we discuss the principle of the S-G method, problems associated with it, as well as the hydrolysis characteristics of inor ganic compounds and metal alkoxides. By way of case study we consider the S-G p rocessing SnO2. We also go on to consider the future of the S-G method.
