Abstract
In order to study the binding possibilities of Mg(II) and Cu(II) and their influence on the chemical composition and properties of xCuO-(50-x)MgO-50P2O5 metaphosphate glasses, these glasses were prepared on the entire composition line. Based on the results of X-ray fluorescence, Raman spectroscopy, electron paramagnetic resonance and 31P MAS NMR, a real chemical composition, i.e. a chemical model, was proposed. The proposed chemical model was verified using the results of various experimental methods characterizing the properties of both the volume and the surface of the glasses, e.g. dilatometry, DSC, Raman spectroscopy and tenziometry. The assumption of the influence of the shielding of the charge of the copper core by its d9 valence electrons was also verified. The experimental results obtained by all the techniques used are discussed in detail.
