Ga3Ir
Ga3Ir is a metallic intermetallic compound composed of gallium and iridium that is recognized for its structural stability and potential utility in catalytic research.
About Ga3Ir
Ga3Ir is a metallic compound belonging to the platinum-group alloy catalyst class. Its electronic structure is characterized by a lack of a band gap, consistent with its metallic nature, which is a key feature for materials involved in electron-transfer processes. The compound is considered near-hull in terms of thermodynamic stability, suggesting it is a viable candidate for experimental synthesis and characterization.
With a significant number of reported structures across multiple databases, this material is a well-documented subject in solid-state chemistry. Its composition of gallium and iridium positions it as a specialized intermetallic phase, potentially useful in catalytic environments where metallic conductivity and structural robustness are required.
Key Properties
Cross-validated computational properties for Ga3Ir, 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.
