Abstract
The structure of silicate-phosphate glass containing the different amounts of phosphorus, magnesium and calcium cations, acting as macroelements was examined by FTIR, XRD and thermal (DTA/DSC) methods.
It has been found that in the structure of silicate-phosphate glass modified by an addition of Mg2+ and Ca2+ there are formed domains characterized by certain degree of ordering of the units present in their composition, while the structure of the newly formed domains is similar to the structure of the crystal compounds formed during crystallization of these glasses.
The changing character of domains structure may be the reason of different chemical activity of glass acting as glassy fertilizers.
