Abstract

The influence of ball milling and subsequent calcination of a 1:1 molar mixture of α-Fe₂O₃ and Li₂CO₃ on the formation of LiFeO₂ has been investigated. Pre-milling was found to lower the temperature of ferrite formation by ca. 200°C and a thermally stable γ-LiFeO₂ phase was found to form in the temperature range 500-600°C. Slow cooling of the pre-milled mixture calcined at higher temperatures resulted in the formation of some LiFe₅O₈.
