[en] Formation of glycero-silicates of the second group metals in glycerine solution of the silicon dioxide was investigated by infra-red spectroscopy. The results of investigation of cadmium acetate dissolution in glycerine solution of silicon dioxide by infra-red spectroscopy are presented. On the basis of data obtained it is possible to assume that introduction of positive aetal ion into glycerine solution of silicon dioxide reduces interaction between hydroxyl groups of glycerine and silane groups of silicon dioxide arised by hydrogen bons during their approaching each other, which leads to the displacement of maxima of oscillations bands of glycerine and SiO₂ groups
