| Abstract: | Raman spectra of ternary sodium aluminosphosphate glasses indicate that for glasses with Al2O3/P2O5<0.63, the glass network is mainly built up of (PO3)nn- chains and rings or different kinds of phosphate groups and AlO4 tetrahedra; for glasses with Al2O3/P2O5>0.63, the glass network is mainly built up of AlPO4 groups. |
