评价了溶胶-凝胶工艺的科学技术意义和重要性。介绍了在硅酸盐体系中制备凝胶的两种方法。第一种方法是基于胶态硅溶胶的凝胶化;第二种方法是基于烷氧基硅烷与金属醇盐或金属盐的聚合，以产生具有网络结构的多组分非结晶无机凝胶。凝胶过程的物理化学原理进行了讨论，在各种工艺参数。描述了凝胶到玻璃的转化。讨论了凝胶和凝胶玻璃的结构、微观结构、相分离和析晶行为与凝胶制备方法的关系。与过程相关的优点进行了检查和评估。提出了玻璃技术中的各种应用。
The scientific and technological significance and importance of the sol-gel processes are evaluated. Two methods for preparing gels in the silicate systems are described. The first method is based on gelling colloidal silica sol; the second method, on the polymerization of alkoxysilane with metal alkoxides or metal salts to produce multiccomponent noncrystalline inorganic gels with network structures. The physico-chemical principles of gelling processes are discussed in terms of various process parameters. The conversion of gel to glass is described. The structures, microstructures, phase separation and crystallization behavior of gels and gel-derived glasses are discussed in relation to the methods of gel preparation. The advantages associated with the processes are examined and evaluated. Various applications in glass technology are suggested.
