Key Properties
Cross-validated computational properties for YCrO4, 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.

How It Compares
Within the spinel oxide catalysts class.
Within the diverse group of spinel and transition metal oxides, YCrO4 occupies a distinct niche compared to simple binary oxides like NiO or ZnO. While materials such as LaMnO3 or LaNiO3 are frequently studied for their perovskite-related catalytic activity, YCrO4 provides a different structural framework that complements the performance profiles of these more common complex oxides.
