Desorption of Kr (or Kr85) and SF6 from Vitreous and Crystalline SiO2, and of Kr from B2O3 and GeO2 Glasses
The diffusion and solubility coefficients of He in various inorganic glasses are well known, while only few data for Ne and Ar are available (1–6). Kr and SF6, a fairly inert and nearly spherical molecule of large size, have been used very little in studies of this sort. It is not clear to what extent the larger molecules can reach subsurface layers or interior regions of typical glasses.
