Above 755°C, compounds along the spinel join LiFe 5 O 8 ‐Li 4 Ti 5 O 12 form a complete solid solution and below that temperature a two‐phase region separates the ordered LiFe 5 O 8 and the disordered spinel phase. At 800° and 900°C, cubic LiFeO 2 ( ss ) and monoclinic Li z Ti0 3 ( ss ) exist on the monoxide join LiFeO 2 ‐Li 2 TiO 3 . The distributions of cations in both the spinel and monoxide structures were calculated as a function of equilibrium temperature and composition. Sub‐solidus equilibria in the system Li 2 O‐Fe 2 O 3 ‐TiO 2 at 800° and 900°C were determined for compositions containing ∼50 mol% Li 2 O.
