摘要：

The structure of various hydrated and untreated glasses of the system Na2O-B2O3-SiO2 was investigated using multinuclear NMR. Two different BO4 units have been detected by B-11 SATRAS (Satellite Transition Spectroscopy) NMR. Comparing the spectra of the untreated and hydrated glasses it was found, that nearly all BO3 units and one of the BO4 units are removed during the reaction of the glasses with hydrous solution. Furthermore, H-1-B-11 REDOR (Rotational Echo Double Resonance) has been used to investigate the incorporation of protons in the hydrated glasses. New aspects containing the structural role of protons are obtained.
