Indium · metallic indium
Indium is a soft, silvery-white metallic element widely used for its excellent bonding and coating properties in electronic devices.
About Indium
Indium is a post-transition metal characterized by its soft, malleable nature and distinct metallic electronic structure. As a thermodynamically stable solid, it maintains a robust crystalline arrangement that makes it a reliable component in various industrial processes. Its unique ability to wet glass and form alloys with other metals allows it to serve as a critical interface material in modern manufacturing. Because it is a highly stable element, it is frequently utilized in thin-film coatings and specialized solders where consistent performance is required. Its widespread study across multiple databases underscores its importance as a foundational material in materials science and engineering.
Key Properties
Cross-validated computational properties for Indium, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of In. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
