“…It was found [9] that the aging rate of a sol rises with a decrease in the concentration of film forming oxides. In the given case, moisture penetrating into the sol during coating application in air favored this process.…”

The influence of the aging period (duration) and the aging related rheological characteristics of film forming solutions (sols) on the refractive index and thickness of coatings, light reflection and light trans mission coefficients, and optical losses in glass substrate-nanodimensional oxide (CuO-TiO 2 ) composites is considered. It has been shown that the increase in the CuO concentration in the coating and the extension of the sol aging period favor crystallization and change the form of inclusions in the coating from pseudospher ical to dendritic with a different degree of branching. The refractive index of the film and its related coefficient of mirror reflection of the composite are functions of the density of packing sol disperse phase particles into a nanodimensional layer. The packing density of dendritic particles drops decreases with the degree of their branching and transverse size of fragments. In every case, an optimal sol aging period should be found to obtain glass composites with nanodimensional coatings offering desired optical properties.

“…The service parameters of glass produced by sol-gel technology to a large extent depend on the type of materials used for film-forming oxides [3], the time-temperature conditions of preparation, maturing, and application of FFS [4,5], etc. Experience shows that when float glass is used as a substrate, the thickness, refractive coefficient, and spreadability of sol-gel coatings on the opposite surfaces differ to a certain extent, which may be related to the different properties of the two sides.…”

The refractive coefficients and thickness of two-sided sol-gel coatings of different compositions deposited on float glass by the immersion method are measured. It is established that the refractive coefficient on the top surface of a sample, which contacts the protective atmosphere of the melt tank during glass working, is higher and the film thickness is smaller than those on the bottom surface. This is due to the different properties of the opposite surfaces of thermally polished glass, which is related to the different tin concentrations in the surface layers.
