Özet
Effects of boron addition on the glass forming characteristics, structure and properties of iron phosphate glasses with nominal compositions of xB2O3–(40−x)Fe2O3–60P2O5 (x=2–20, mol%) and xB2O3–(100−x)[Fe2O3–60P2O5] (x=2–20, mol%) have been investigated by DTA, XRD, IR and Mössbauer spectroscopy. Although there were some weak local surface crystallizations on especially most of the glasses in group B, all of the compositions formed glass. DTA spectra showed two exothermic peaks corresponding to crystallizations along with an endothermic glass transition peak. Tg increased with increasing B2O3 content for the glasses in the first series which indicates that the addition of B2O3 increases the thermal stability of glasses in this series while the opposite is observed in the second series. The dissolution rates of boron containing bulk glasses were found to be around 10−9gr/cm2 min which are …
