MgTi2Al4O10
MgTi2Al4O10 is a semimetallic quaternary oxide containing magnesium, titanium, and aluminum that is currently being investigated for its structural properties.
About MgTi2Al4O10
MgTi2Al4O10 is a complex quaternary oxide composed of magnesium, titanium, aluminum, and oxygen. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime, which distinguishes it from typical insulating oxide ceramics. Given its position above the thermodynamic hull, this compound is likely unstable under standard conditions. It remains a subject of interest for researchers studying the structural diversity of multicomponent oxides, with multiple reported structural configurations documented in databases.
Key Properties
Cross-validated computational properties for MgTi2Al4O10, aggregated across 2 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
