Abstract

The paper analyses the influence of heat treatment parameters on SiO2 coatings obtained by the sol–gel technique. Their adhesion to the glass substrate and corrosion resistance were studied. The changes in thickness and porosity with the firing temperature and time of sintering for the systems of 1, 2 and 3 layers in case of SiO2 layers were studied. It was shown that the sufficient durability of the SiO2 coating on the glass substrate can be achieved only by the appropriate selection of thermal treatment parameters. The results confirmed that higher sintering temperature is required for multilayer systems, as compared with a one-layer system.
