Phase Equilibria and Structural Studies on the Solid Solution MgTi2O5-Ti3O5

TinO2n−1Magnéli phases studied using density functional theory

“…The Ti 3 O 5 structure obtained from crystallographic databases was not unique. The three phases, α (orthorhombic, anosovite-like, group Cmcm) [50], β (monoclinic, group C2/m) [51,52], and γ -Ti 3 O 5 (monoclinic, I 2/c) [53] were used for the calculations. Onoda et al pointed out a first-order phase transition at approximately 440-460 K [54] between α and β-Ti 3 O 5 .…”

Magnesium dititanate (MgTi2O5) with pseudobrookite structure: a review

“…Similarly to isomorphic compounds, Fe 2 TiO 5 (pseudobrookite) and Al 2 TiO 5 (AT, tialite, tielite or tieilite), the crystal structure and crystal chemistry of MgTi 2 O 5 have been studied in detail [11,29,30]. Table 1 and figure 1 present the crystal structure of MgTi 2 O 5 reported by Grey et al in 1994 [30].…”

“…Table 1 and figure 1 present the crystal structure of MgTi 2 O 5 reported by Grey et al in 1994 [30]. Note that the axis settings differ from paper to paper; many researchers use the Bbmm notation, following the initial report on Fe 2 TiO 5 (pseudobrookite) by Pauling in 1930 (B-centered; b is the longest and c is the shortest axis) [31].…”

“…63 in the International Tables [11]. In table 1, another notation Ccmm used by Grey et al [30] was converted into the Cmcm notation.…”

X‐ray diffraction refinement of the crystal structure of anosovite prepared from leucoxene

“…The same effect is expected to occur in our experiment. As claimed in [26,29] and also as shown in figure 2, the structure of anosovite has two crystallographically independent cation sites, labeled M1 and M2, both of which are octahedrally surrounded by oxygen atoms. The MO 6 octahedra form a characteristic row extending…”
