摘 要：The structure of V₂O₅-P₂O₅-Sb₂O₃-Bi₂O₃ glass and its state of crystallization were studied by means of infrared spectroscopy and X-ray diffraction analysis. The results indicate that, in this glass, V and P exist mainly in the form of a single-stranded linear （VO 3 ） n and an isolated （PO 4 ） tetrahedral with no double bond. Partial V and P are connected through O, forming an amorphous structure of layered vanadium phosphate. Trivalent Sb 3+ and Bi 3+ open the V=O bond and appear in interlayers, so a weak three-dimensional structure is connected successfully. Along with the substitution of Sb 2 O 3 for partial V 2_O5 or that of P₂O₅ for partial V₂O₅ , the network structure of the glass is reinforced, and the crystallization is reduced.
