Hydrogen Permeability of Silicate Glasses

详细

Glasses in the silicate, borosilicate, aluminum-silicate, and aluminum-boron-silicate systems are studied. Expressions are obtained for determining the activation energy of hydrogen permeability and the hydrogen permeation rate as a function of the content of all, without exception, components present in the experimental glasses and for comparing glasses of different compositions in terms of permeability and permeability of glasses upon heating. The ranges of these criteria are determined. It is shown that silicate glasses impermeable for hydrogen do not exist.
