Well-controlled fine MgTi₂O₅ &ensppowders, with pseudobrookite-type structure, are desired toward various industrial applications, however, commercial powders are hardly available to date. In this study, we focused the processing and characterization of well-controlled MgTi₂2O₅ &ensppowders with/without LiF additive. MgCO₃ &ensp(basic) and TiO₂&ensp anatase powders with/without 0.5 wt. % LiF additive were calcined in air at 1100 °C for 2 h to obtain the MgTi₂O₅ &ensppowders. SEM observation revealed that the non-doped MgTi₂O₅ &ensppowder consisted of equiaxed particles with the diameter of 0.51.5 μm, whereas, the LiF-doped MgTi₂O₅ &ensppowder consisted of elongated particles with the length of ~ 5-10 μm and the diameter of ~1.0-1.5 μm. The smooth surface of elongated MgTi₂O₅ &enspparticles demonstrates the effect of LiF doping as a flux, i.e., liquid phase formation during the reaction.
