Binding possibilities of calcium, zinc and copper in metaphosphate glasses - a more detailed study
Original language description
To study the binding possibilities of Zn2+, Ca2+ and Cu2+ ions in the glassy phosphate network, metaphosphate glasses of xZnO-(50-x)CuO-50P(2)O(5) and yCaO-(50-y)CuO-50P(2)O(5) systems were prepared across the entire composition lines. Using Raman spectroscopy, P-31 MAS NMR, electron paramagnetic resonance (EPR) and differential scanning calorimetry (DSC), it was found that zinc and copper are both four times coordinated and interact with donor oxygens in the same phosphate chain, calcium is six times coordinated and crosslinks phosphate chains significantly increased by this the glass transition temperature. It was further found that all copper-containing glasses are phase separated, which is also clearly reflected, in addition to the P-31 MAS NMR and EPR spectra, in the compositional dependence of the glass transition temperature. The experimental results obtained by all the techniques used are discussed in detail.
