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 2O5 or that of P2O5 for partial V2O5 , the network structure of the glass is reinforced, and the crystallization is reduced.
