The nanoporous sodium-borate-silicate glasses Na 7/23 (standard symbol) with pore sizes within 5-100 nm have been investigated. The X-ray investigations in wide and small angles allowed us to determine some important parameters of glassy framework: the percentage distribution of pore sizes being in the vicinity of 8 nm and 80 nm; fractal dimensionality of porous glass being of 20 (8 nm pores) and 1.81 (80 nm); crystallinity grade within the vitreous bulk being of 7% (8 nm) and 9% (80 nm) phase composition of crystalline areas within the silica framework. The nanoclusters of crystallohydrates on the basis of cobalt(II) chloride supported on the inner surface of nanopores have been characterised
