Correction to the phase equilibria in the FeMnTiO system

The reported phase relations for the FeMnTiO system (R. R. Merritt, J. Solid State Chem., 43, 267, 1982) have been redetermined because they were found to be affected by the presence of 1.34 wt% Al₂O₃ in the TiO₂ used. This impurity lowers the temperature at which the pseudobrookite phase is stable. The results of the new work reaffirm the changes to the phase diagram that result from the replacement by manganese of part of the iron in the FeTiO system. On the basis of the earlier results, a phase diagram is proposed for an aluminum-containing five-component system.
