AlNi3
AlNi3 is a stable metallic intermetallic compound formed from aluminum and nickel.

About AlNi3
AlNi3 is a metallic intermetallic compound composed of aluminum and nickel. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration that maintains its integrity under standard conditions. Its metallic nature is defined by the absence of a band gap, facilitating efficient electron transport characteristic of such intermetallic systems. This compound is of significant interest in materials science due to its structural stability and the well-documented nature of its atomic arrangements. With numerous reported structures across multiple databases, it serves as a foundational reference point for understanding the phase behavior and bonding characteristics of aluminum-nickel systems.
Key Properties
Cross-validated computational properties for AlNi3, 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.
