High Temperature Behaviour of Hercynite
Hercynite (FeAl2O4) was obtained by Arc Plasma Synthesis (APS) and thermally annealed at 1000 °C for 1, 24 and 36 h respectively, in air. The XRD measurements, that were conducted before and after the annealing, showed an evident alteration of the original hercynite under the influence of temperature and oxygen access.
