Presented were the results of investigation of hygroscopicity of coatings of low-hydrogen electrodes depending on composition of liquid Li-, Na- and K-glasses as well as their binary mixtures, which were interpreted from point of view of evolution of a silicon-oxygen structure in the process of glass formation under effect of changing type and relationship of cations of alkali metals. Carried diagnostics of structure-functional self-organization of the silicon-oxygen anions in composition of the liquid glasses was performed based on data of a nuclear magnetic resonance. The spectra of nuclear magnetic resonance 29Si were used. Generalized data were considered taking into account dominance of polycondensation mechanism. Correlation between the indices of coating hygroscopicity and relationship of bridge Q4, Q³, Q² and nonbridge Q¹ connectivities in structure of the silicon-oxygen anions were determined.
