Magnesium dititanate (MgTi2O5) with pseudobrookite structure: a review

Magnesium dititanate (MgTi 2 O 5 , MT 2 ) has been synthesized since the early 1930s. It has the pseudobrookite structure (general formula Me 3 O 5 ), corresponding to the Mg-enriched artificial endmember of the Fe 2 TiO 5 (pseudobrookite)-FeTi 2 O 5 (ferropseudobrookite)-Mg 0.5 Fe 0.5 Ti 2 O 5 (arm...

Summary:Magnesium dititanate (MgTi 2 O 5 , MT 2 ) has been synthesized since the early 1930s. It has the pseudobrookite structure (general formula Me 3 O 5 ), corresponding to the Mg-enriched artificial endmember of the Fe 2 TiO 5 (pseudobrookite)-FeTi 2 O 5 (ferropseudobrookite)-Mg 0.5 Fe 0.5 Ti 2 O 5 (armalcolite) solid solution. Since MgTi 2 O 5 has relativity high thermal stability among pseudobrookite-type phases, it is expected to be a well-balanced low-thermal-expansion material. Here we review both the historical and recent studies on MgTi 2 O 5 , particularly on its crystal structure, cation order-disorder, physical properties and synthesis methods.
