About CrPb2O5
CrPb2O5 is a complex oxide that functions as a semiconducting material within the broader family of spinel-related catalysts. Its position on the thermodynamic convex hull highlights its inherent stability, making it a robust candidate for chemical processes that require structural integrity under varying conditions.
This material is of significant interest in materials science due to its specific electronic character, which facilitates catalytic activity. By leveraging its stable crystal lattice, researchers investigate its potential to drive efficient chemical transformations in industrial and laboratory settings.
Key Properties
Cross-validated computational properties for CrPb2O5, aggregated across 3 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 CrPb2O5. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.

How It Compares
Within the spinel oxide catalysts class.
Unlike the simpler binary oxides such as NiO or ZnO, CrPb2O5 represents a more intricate structural arrangement within the spinel oxide class. While compounds like MgAl2O4 serve as classic structural archetypes for the group, CrPb2O5 offers unique electronic properties that distinguish it from the more common perovskite-structured members like LaMnO3 or LaAlO3.
