摘要：

Multicomponent glasses from the SiO2-P2O5-K2O-MgO-CaO-CuO system acting as slow release fertilizers were synthesized by the melt-quenching technique. The influence of CuO and P2O5 addition on the structure of glasses was evaluated by FTIR, Raman, P-31, and Si-29 MAS NMR spectroscopies. The studies showed that the Cu2+ ions displacing Ca2+ ions and Mg2+ ions in the structure of glass prefer to associate with the phosphorus Q(1) species, forming the Q(0) species with chemically stable P-O-Cu bonds. This is accompanied by the reduction of the degree of polymerization of the phospho-oxygen sub-network, with a simultaneous increased degree of polymerization of the silico-oxygen sub-network of the silicate-phosphate glasses.
