MgO3Si
MgO3Si is a wide-gap insulating magnesium silicate compound that is theoretically stable and serves as a subject of interest for structural materials research.
About MgO3Si
MgO3Si is an insulating compound composed of magnesium, oxygen, and silicon. Its electronic structure is characterized by a wide band gap, which is typical for stable oxide-based materials that exhibit insulating behavior in their ground state. The material is considered near-hull in terms of thermodynamic stability, suggesting it is a viable candidate for experimental synthesis and further laboratory investigation. With numerous reported structures across multiple databases, it represents a significant subject for structural analysis within the field of inorganic chemistry. This compound is of particular interest to researchers investigating the fundamental properties of ternary magnesium silicates and their potential applications in high-performance dielectric or structural systems.
Key Properties
Cross-validated computational properties for MgO3Si, aggregated across 4 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.
