Silica was coated on the surface of soda lime silicate glass by dipping using a polycarbosilane solution and heat treatment was done in the air. The composition and the structure of these films were evaluated using XPS, FESEM, FT-IR, Anti abrasion test, fluoric acid etching test, and sodium leaching test, etc. and they were compared with those of uncoated soda lime glass. The results showed that these films made using solution process had a dense structure and a great alkali barrier effect. After heat‐treatment at 550oC, the structure of these films became denser, getting close to that of fused silica. |
