xCdO.(100-x) (yNa2O.zP2O5) invert glasses, with CdO substituted for both Na2O and P2O5 were successfully prepared using a melt-quenching method.x changed up to 45 mol% and z equals y in all cases.31P NMR studies show that CdO replaces both Na2O and P2O5, the total concentration of nonbridging oxygen atoms (NBO) increases.CdO switched its role of ne
