【 摘 要 】

High temperature oxidation properties of MgF2in air were studied. The changes of phase composition, macro surface morphology, weight and elemental composition of MgF2samples with temperature were investigated by using XRD, EDS and gravimetric analyses. The results show that the oxidation reaction of MgF2converted to MgO occurred at high temperature, and the reaction was accelerated by the increase of temperature and the presence of impurities. This result clarifies the understanding of the high temperature oxidation behavior of MgF2in air, and provides a theoretical basis for the reasonable application of MgF2in optical coating materials, electronic ceramic materials and magnesium melt protection.
