Borosilicate glass-forming compositions R 2 O - B 2 O 3 - SiO 2 - R a < / sub> O b (R - Li, Na, K; Ra - Zn, Pb). Correlation-regression analysis of the criteria influencing their hydrogen permeability is carried out: silicate modulus, oxygen number, structure connectivity factor, relative molar volumes of components. The tendency of permeability change is determined depending on the component composition and the specified criteria. Tab. 2, ill. 3, bibliography: 9 titles.
