Different multicomponent solutions have been developed by which building materials were coated. After drying and annealing, the coatings convert into silicate based glassy films. TEOS or fumed silica were used as silica carriers and by adding lead compounds also low melting compositions were prepared. In some cases it proved to be convenient to adjust the viscosity of the solutions by additions of suitable organic polymers. The heat treatment was done either in an electric furnace or by means of a special acetylene burner. The produced films can protect building materials against corrosion, may reduce the absorption and permeation of water or improve abrasion resistance.

Dielectric properties of R2O−SiO2 glasses prepared via sol-gel

Gels from R20-SiO 2 (R = potassium, sodium and lithium) systems with a maximum alkaline content of 5 mol % were prepared. The conductivity and the alkaline ion incorporation degree as a function of temPerature were studied by a.c. impedance spectroscopy and dielectric relaxation measurements. At low temperature (20 to 200 ° C) the major contribution to the total electric conductivity is due to water conducting species (mainly protons) which are adsorbed inside the gels. From 450°C gels start to behave as conventional glasses. The total electric conductivity and activation energy values for conduction at those high temperatures are of the same order as those for glasses prepared by direct melting.
