Abstract

Glass ceramics samples with chemical composition (Fe2O3)x·(P2O5)40·(ZnO)(60-x) (0 ≤ x ≤ 20 mol%) were prepared by melt-quenching technique, followed by a thermal treatment at two different temperatures for two hours. Structural properties were studied by DTA, XRD, and FTIR measurements. From DTA measurements can be observed that, with increasing in concentration of the dopant (Fe2O3), the transition and crystallization temperatures increase. The XRD data show, the presence of two or three crystalline phases, and the FTIR data confirm the existence of ZnO4 structural units in our samples. So, the thermal treatment applied to the samples lead to changes in the structural properties and also to some modification in the glass ceramic network.
