MgSi2SnO6
MgSi2SnO6 is a metastable, insulating quaternary oxide composed of magnesium, silicon, tin, and oxygen.
About MgSi2SnO6
MgSi2SnO6 is a complex oxide composed of magnesium, silicon, tin, and oxygen. As a wide-gap insulating material, it exhibits electronic properties characteristic of dielectric oxides, making it a subject of interest for fundamental solid-state studies.
Although it is classified as a metastable phase, the existence of multiple reported structures highlights its structural flexibility. This compound serves as a valuable case study for understanding phase stability in multi-component oxide systems.
Key Properties
Cross-validated computational properties for MgSi2SnO6, aggregated across 3 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.
