From the structural and morphological results, the lithium ferrite crystal phase obtained is the ordered one, α-LiFe 5 O 8, and is mostly present in the samples with thermal treatment from 1000 to 1200°C. Heat treatments above 1150°C promote the formation of the Li 2 FeO 3 and Fe 3 O 4 crystal phases.
According to the Raman spectroscopy spectra, all the samples show the vibration mode characteristic of both ordered and disordered lithium ferrite phases. For the samples treated between 1000 and 1400°C, the vibrational peaks at 199–206 and 237–241 cm −1 indicate the presence of the ordered α-LiFe 5 O 8 phase [ 18 ].
