    Corrosion of Glass
    (Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 2004) Helebrant, A.; Jiřička, A.; Jiřičková, J
    The paper reviews the different models describing interaction between glasses and aqueous solutions. It is shown the development of kinetic and thermodynamic models (Rana & Douglas, HIaváč & Matěj, Isard et al., Boksay & Doremus, Strachan, Grambow, Conradt, Aagaard & Helgeson). The models are compared from the point of view of different mechanisms and partial processes considered during model development. Model based on combination of Boksay & Doremus and Strachan models is shown, considering the glass corrosion as a combination of three simultaneous processes: 1. Glass matrix dissolution with two subsequent steps (surface reaction and surface reaction products transport through the precipitated layer and/or through Solution layer adjacent to the glass surface) 2. Leaching of moveable ions (A⁺) due to interdiffusion of HsO⁺ - A⁺ 3. Precipitation of dissolved glass components and/or Solution components on the glass surface. Finally, the outlook for future development of glass corrosion modelling is suggested, based on combination of Boksay & Doremus, Strachan, Conradt and Aagaard & Helgeson approach.
