Mass transfer coefficients for water at silica surfaces : Additional results

Monotonously increasing water concentrations at silica surfaces can be described by a mass transfer surface condition for diffusion that hinders free water penetration from a water vapour environment into silica. So far, the related mass transfer coefficient has been determined predominantly from water uptake measurements. In this report, the data basis will be extended by taking into consideration further literature results on measurements of surface water concentrations and by evaluation of disk curvature measurements.
