Abstract
In this chapter, the authors present state of the art and formation of sol-gel technology of obtaining multifunctional hybrid silicate materials with technically improved properties. The crucial steps and new approaches to establish the mechanism of formation of noncrystalline systems (sols and products of sol-gel synthesis) are substantiated to be study of the fractal structure of sols, gels and synthesized silicate nanocomposites. The use of sol-gel technology is proved to be especially relevant for the formation of new silicate materials and coatings required for power engineering. New products of sol-gel synthesis, such as catalytic coatings for gas sensors and next-generation electrochemical devices, are shown to be extremely necessary in transport engineering, as well as to ensure the safety of harmful industries, mining, agriculture, and everyday life.
