| Abstract: | Through measuring the alkali resistance of the invert glass and the quantity of SiO 2 and TiO 2 migrating fron the glass into the solution,the influence of TiO 2 on the alkali resistance of the glass is discussed and its structure is also analyzed by infrared spectroscopy.It is concluded that TiO 2 has double functions for the alkali resistance of the invert glass.On the one hand ,both TiO 2 polarizing the secondary ions in glass and TiO 2 isomorphism replacement of SiO 2 make the alkali resistance of the glass decrease.On the ther hand,TiO 2 patching network and anti erosion covering help to increase the alkali resistance. |
