In3Ni2
In3Ni2 is a stable metallic compound formed from indium and nickel that is frequently documented in materials science databases.
About In3Ni2
In3Ni2 is a metallic intermetallic compound composed of indium and nickel. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement within the indium-nickel binary system. Its metallic character suggests high electrical conductivity, typical of transition metal-post transition metal alloys.
This compound is of significant interest to materials scientists studying phase stability and alloy design. Its existence as a well-defined, stable structure across multiple databases highlights its importance as a benchmark for computational and experimental studies in metallurgy.
Key Properties
Cross-validated computational properties for In3Ni2, 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.
