Mg8Sr4
Mg8Sr4 is a stable, metallic intermetallic compound formed from magnesium and strontium.
About Mg8Sr4
Mg8Sr4 is a metallic intermetallic compound composed of magnesium and strontium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration within the binary alloy system. Its metallic nature is defined by the absence of a band gap, indicating high electron mobility characteristic of intermetallic phases.
This compound is of significant interest in materials science due to its structural complexity and stability. With numerous reported structures across multiple databases, it serves as a key reference point for understanding the phase behavior and atomic arrangements in magnesium-rich alkaline earth alloys.
Key Properties
Cross-validated computational properties for Mg8Sr4, aggregated across 5 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.
