Abstract

In recent years there were many messages about development and use of a new class of materials – aero gels of various structure. Aero gels represent solid substance with very low density and a large number of the time filled with air or gas. Aero gel has low heat conductivity, index of refraction of light, dielectric permeability and speed of distribution of a sound. Modern technologies allowed to begin mass production of aero gels of dioxide of silicon which find more and more broad application at production of thermal insulation for industrial and construction use. This article submits the review of the heat-insulating materials intended for protection both from high, and from low temperatures, with use of aero gels.
