Cr2Ni
Cr2Ni is a metallic chromium-nickel intermetallic compound that exists in a metastable state.
About Cr2Ni
Cr2Ni is a metallic intermetallic compound composed of chromium and nickel. As a metallic system, it exhibits characteristic electron delocalization and conductivity typical of transition metal alloys.
While it has been documented across multiple structural databases, the compound is characterized as being thermodynamically metastable. Its existence as a phase above the hull suggests that it requires specific synthesis conditions to stabilize its atomic arrangement.
Key Properties
Cross-validated computational properties for Cr2Ni, aggregated across 4 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.
