Abstract
Water, ethanol, and hydrochloric acid containing solutions of silicon ethoxide, titanium butoxide, and zirconium pro-poxide have been developed which show a constant viscosity for some days. The influence of formamide additions on the viscosity behavior was studied too.Glass slides have been dip coated in the solutions, dried in ethanol containing atmosphere, and baked at 300 ° C. Multilayered films were obtained by repeating this procedure. After a final baking at 500 ° C, crack-free transparent SiO2-TiO2-ZrO2 glassy films have been obtained. Compared to the substrate, the films of thicknesses below 500 nm were very stable against hot NaOH solution. The stability of the coatings was analyzed by detection of the remaining TiO2 and ZrO2 in the films after the attack. This was done by a x-ray fluorescence (XFA) technique.Keywords
