RuW
RuW is a metallic binary alloy of ruthenium and tungsten that is often studied for its complex structural properties within the platinum-group catalyst family.
About RuW
RuW is a metallic intermetallic compound belonging to the class of platinum-group alloy catalysts. Its electronic structure is characterized by a lack of a band gap, consistent with its metallic nature, making it a subject of interest in fundamental studies of transition metal bonding and alloy behavior.
Despite its classification as a potential catalyst, the compound is identified as being above the thermodynamic hull, suggesting it is metastable under standard conditions. Its high structural data richness across multiple databases underscores its importance as a model system for understanding complex phase formation in binary ruthenium-tungsten systems.
Key Properties
Cross-validated computational properties for RuW, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.

How It Compares
Within the platinum-group alloy catalysts class.
Unlike more stable or commercially established platinum-group compounds like P3Ru or LaRh, RuW exists in a metastable state. While many members of this class are optimized for specific catalytic pathways, RuW serves primarily as a structural reference point for exploring the limits of phase stability within high-density transition metal alloys.
