摘要：

New alkali resistant BaO-TiO2-SiO2 coatings have been developed via the sol-gel process. In the solutions and in the gels (T < 300 degrees C) an infrared absorption band at 930 cm(-1) gives the possible evidence of mixed Si-O-Ti bonds, which have not been found in the system SiO2-TiO2-ZrO2. Baking the films at about 500 degrees C for less than 1 h leads to stable layers with negligible residual carbon contents. Compositions near 20 BaO-40 TIO2-40 SiO2 showed the best performance.
