Abstract: | Through measuring the alkali resistance of the invert glass and the quanity of SiO2 and TiO2 migrating fron the glass into the solution, the influence of TiO2 on the alkali resistance of the glass is discussed and its structure is also analyzed by infrared spectroscopy. It is concluded that TiO2 has double functions for the alkali resistance of the invert glass. On the one hand, both TiO2 polarizing the secondary ions in glass and TiO2 isomorphism replacement of SiO2 make the alkali resitance of the glass decrease. On the ther hand, TiO2 patching network and anti-erosion covering help to increase the alkali resistance.
