Mg5H8O9
Mg5H8O9 is a stable, wide-band-gap insulating compound composed of magnesium, oxygen, and hydrogen.
About Mg5H8O9
Mg5H8O9 is a complex hydrogen-containing magnesium oxide that exists as a thermodynamically stable phase on the convex hull. Its electronic character is defined by a wide band gap, classifying it as a robust insulating material suitable for applications where electrical conductivity must be minimized.
Because it is a stable inorganic compound, it serves as a fundamental building block in structural investigations of magnesium-based systems. Its existence across multiple databases highlights its significance as a well-defined crystalline phase within the broader landscape of metal-oxygen-hydrogen materials.
Key Properties
Cross-validated computational properties for Mg5H8O9, 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.
