Sol-gel process preparation of functional silica materials and their application

Abstract

The development of new high-performance materials for electronic, optical-mechanical and other industries is restrained by traditional mode of their production. It concerns materials technologies based on physical processes, for example, fusion and sintering, which require heat treatment and high pressure. The synthesis of materials with new properties is possible using chemical, colloid processes. In this respect the processes of transition of a sol into a gel, and further into a solid body with particular properties, is the basis of development of new sol-gel technologies.
