Fluorophosphate glass is used as a kind of optical glass and laser material. Based on studying the formation and structure of A1(P03)3 contained fluorophosphate glass, in the present work, the optical and other physical properties of the above glass have boon investigated. The low A1(P03)S content fluorophosphate glass,in which the network structure has been destroyed seriously, is located in destroyed region, the variation of the glass properties and the effect of various fluorides on the properties are similar to those of the oxide glass in destroyed region.The special role of LiF,MgF2,AlF3 is also reflected on the variation of the physical properties. Moreover, compared with silicate and borate glasses with high contents of glass formers, the electrostatic attraction between cations and anions plays more important role to variation of the properties of the fluorophosphate glass with low Al(P03)3 content. The position of the studied glass in n vs. v diagram is plotted, the partial properties of the studied glass are given and compared with some literature data, and the variation of the partial properties have been related to the Al (PO3) 3 content.
