Helium permeability, diffusion, and solubility were measured in sodium silicate glasses containing 0 to 40 mol% Na2O. These properties appear to depend on the substructure of the glass, since definite inflections occur in the curves of diffusivity and solubility vs composition at the boundaries of the two-phase region. Similar inflections occur for the activation energy for diffusion and enthalpy of solution at the phase boundaries. These effects are explained by use of a two-component diffusion model within the miscibility gap and a one-component model in the single-phase region.
