Abstract

Glasses of theK2O−MgO−CaO−SiO2 and K2O−MgO−CaO−P2O5−SiO2 systems with microelements (Fe, Mo, Zn, B, Mn, Cu) were obtained by melting of apatite and serpentinite rocks, K2CO3 and oxides of appropriately metals mixtures. The amorphous state of glasses and the structural changes during their heating were determined by RDF and DTA/DSC methods. The solubility of the glasses in 2 mass% citric acid solution was studied by chemical analysis (ICP-AES, EDS) and SEM observations.

It has been found that the biochemical activity of silicate-phosphate glasses depends on the content of P2O5 and K2O in their framework and is related to crystallisation ability of these glasses.
