| Abstract: | LiFe5O8 was synthesized by the self-propagating high temperature combustion synthesis using lithium acetate and iron acetate as starting
materials and glycine as reductant. The reaction was rapid when the ignition temperature was reached and the product was a
light and porous mass of solid material. Analysis using X-Ray powder diffraction and SEM revealed the amorphous nature of
the LiFe5O8 precursor material. From particle size analysis, the precursor material was much less than 100 nm, but increased upon annealing
at 650 °C and 900 °C.
