The Sol-Gel Technology of Porous Composites

The present work analyzes patterns of change, composition, structure and properties of porous composite materials, and presents the main types of them. The selection of chemicals that have the greatest thermal stability and fire resistance was carried out. Physical and chemical characteristics of main porous refractory materials were shown. The materials with regular and quasiregular pore structure, as well as materials with the pore structure of opal are given as the example.
