B2Ru
B2Ru is a stable metallic alloy composed of ruthenium and boron used primarily in catalytic research.
About B2Ru
B2Ru is a metallic platinum-group alloy that occupies a stable position on the thermodynamic convex hull. Its structural integrity and electronic properties make it a subject of significant interest within the field of transition metal borides and catalysts.
As a highly characterized material with extensive structural data, B2Ru serves as a fundamental building block in the study of ruthenium-based alloys. It is primarily utilized in research contexts where stable, metallic catalysts are required for advanced chemical transformations.
Key Properties
Cross-validated computational properties for B2Ru, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of B2Ru. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
