Abstract
The influence of Al content on the high-temperature oxidation of MgF2 in an air/HFP atmosphere at temperatures ranging from 700 to 1000 °C has been studied with XRD and EDS. The results reveal that the addition of Al accelerated the oxidation of MgF2. With increasing Al content in MgF2, the oxidation of MgF2 was increased. At the same Al content, the oxidation of MgF2 also increased as the temperature rose. These results suggest that the increase of the Al content of MgF2 and the temperature decreased the high-temperature stability of MgF2.
