The high bulk and surface electrical resistivity of commercial glass can be altered by applying thin conducting coatings, e.g. by sol-gel methods. The effect of composition and processing parameters on film resistivity was estimated. Film forming alcoholic solutions were prepared using tetraethoxysilane, tetraethoxytitane, zirconium oxychloride, HCl-dissolved oxides of Sb, In, Bi, La, the chlorides of Fe and Co, and AgNO3. The films were applied to thermally polished sheet glass and heat treated at 350-550 C for 0.5-1 h. An increase in the oxide concentration in the film-forming solution lowers the resistivity, while introduction of Fe increases the resistivity. The effect of oxides depends on the cation electronegativity; the larger the latter, the lower the film resistivity. As the heat treatment is increased, the resistivity of the films is reduced. These results can serve as the basis for selecting compositions and process methods for producing quality, electrically conducting coatings on glass using the sol-gel method.
