Cd3Ir
Cd3Ir is a metallic cadmium-iridium alloy that serves as a research subject in the study of platinum-group intermetallic compounds.
About Cd3Ir
Cd3Ir is a metallic compound categorized within the platinum-group alloy catalysts. As a material lacking a band gap, it exhibits characteristic metallic conduction, making it a subject of interest for researchers investigating the electronic properties of iridium-based intermetallics.
Despite its existence in multiple structural databases, the compound is identified as being above the thermodynamic hull, suggesting it is metastable under standard conditions. Its study contributes to the broader understanding of phase stability and catalytic potential in complex cadmium-iridium systems.
Key Properties
Cross-validated computational properties for Cd3Ir, 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.
