ESCA, in combination with ion sputtering, was used to obtain compositional depth profiles of complex glasses which had been leached in DI water. The earliest and most obvious feature of aqueous attack was alkali depletion from the near surface regions of the glasses. Further corrosion was slowed by a surface buildup of various elements, which included aluminum, iron, nickel, titanium, zirconium, cerium, and neodymium. Elemental releases were calculated from the ESCA results, which were corrected for variations in the sputter rate through the reaction layer, and compared to those measured directly by ICP solution analysis. The degree of agreement between the two methods was used to assess the importance of matrix dissolution in addition to selective component leaching in the aqueous corrosion of the glasses.
