Abstract

Abstract: The colored film of CoO-CuO-SiO₂ system was prepared by sol-gel method. The effect of several factors, such as concentration of oxides, viscosity of coating solution, heating temperature and heating time on optical transmittance of the film were examined and the compositions for homogeneous glass films were determined. The homogeneous films can be produced only from the system containing more than 50 mol% SiO₂. Both Co²⁺, and Cu²⁺ ions were shown not to take part in network bonds formation.

Key words: sol-gel method, coating film, silicate
