Film formation in two-component sol-gel systems

The film-forming ability of two-component systems containing Sb ₂ O ₃ , SnO ₂ , CeO ₂ , Y ₂ O ₃ , Nd ₂ O ₃ , Bi ₂ O _{3 , V 2 O 5 , ZnO, CuO, CdO and Al 2 O 3 . The best film-formers are Sb 2 О 3 and SnО 2 , and ZnO, CuO, CdO and Al 2 О < sub> 3} optical quality films are not formed. The rest of the studied oxides at a molar content of 20 - 50% do not worsen the transparency of the coatings. A proportional relationship was established between the refractive index and the reflection coefficient of the films and the refractive indices of the oxides included in their composition, as well as between the concentration of the applied POR, the film-forming ability of the oxides, and the thickness of the films.
