Zusammenfassung: | The interaction of water vapor with borosilicate (BS) glass (Corning 7740) at a temperature of 97°C is studied by the method of secondary-ion mass spectrometry. Hydration experiments are carried out over a time period from one day to six months. The profiles of hydrogen distribution in glass are determined by a layer-by-layer analysis using a time-of-flight mass spectrometer. It is experimentally shown in this study that the hydrogenated layer on the surface of soda borosilicate glass growths linearly with time during the first two weeks of hydration (the hydration temperature used in the work) and the thickness of the hydrogenated layer increases in accordance with the parabolic law, i.e., in proportion to the square root of the processing time, starting from the fourth week of the treatment. |
