Glass samples in the systems of (P2O5)75-(CuO)25-X- (CdO)X,(P2O5)75-(CuO)25-X-(ZnO)X, (P2O5)75-(CuO)25-X-(V2O5)X, (P2O5)50-(TeO2)50-x-(ZnO)X, (P2O5)50-(TeO2)50-X-(CdO)X and (P2O5)50(TeO2)50-X-(V2O5) X of different compositions where(X=0,5,10,15, 20)were prepared by the melt-quenching technique.
Density measurements of (P2O5)75-(CuO)25-x-(CdO)x,(P2O5)75-(CuO)25-x–(ZnO)x and (P2O5)50-(TeO2)50-x-(CdO)x show decreasing in density with the increasing of CdO and ZnO contents. The density of (P2O5)75-(CuO)25-x-(V2O5)x,(P2O5)50-(TeO2)50-x-(ZnO)x and (P2O5)50- (TeO2)50-x-(V2O5)x glasses show increasing in density with the increasing of V2O5 and ZnO contents in the glass.The infra-red spectra were recorded for (P2O5)75-(CuO)25-x-(CdO)x,(P2O5)75-(CuO)25-x–(ZnO)x and (P2O5)75-CuO)25-x-(V2O5)x The band positions of such glasses show that (475.27-503.15) cm-1can be attributed to (PO4)-3,The infra-red spectra of (P2O5)50-(TeO2)50-x-(CdO)x,(P2O5)50-(TeO2)50-x-(ZnO)xand(P2O5)50-(TeO2)50-x- (V2O5)x were recorded in the range(4000-400) cm-1.The band positions of such glasses shown that(494.83-498.77)cm-1can be attributed to Te-O-Te linkages
