    Abstract:

    To improve the ability of anticrystallization,P2O5 was introduced to substitute CdF2 in the fluoride glass,consisting of 20GaF315InF320CdF215ZnF210SnF220PbF2(GICZSP).The effect of P2O5 contents on crystallization stability and structure was studied by differential scanning calorimetry (DSC),Raman spectroscopy and XRay Diffraction analyses (XRD).The results indicate that P2O5 can improve the crystallization stability.P2O5 exists as [PO4-4,Q0] tetrahedron which has no PO bond.When the amount of P2O5 being increased,a new M[O,F]6 octahedral structure emerges.
