The DSC, XRD, FTIR, and 31P MAS-NMR methods were applied to study complex crystallization processes occurring during the thermal treatment of multicomponent SiO2–P2O5–K2O–CaO–MgO glasses modified by the addition of variable amount of copper. The crystallization temperatures were found to decrease with the increasing copper content. The products of multistage crystallization identified by XRD and characterized by FTIR and NMR are the Ca9KMg(PO4)7 and Ca19Cu2(PO4)14 phosphates of whitlockite-type, and the CaMgSi2O6 and Cu0.69Mg1.31Si2O6 silicates of diopside type.
