CaIO2
CaIO2 is a semiconducting, metastable inorganic compound containing calcium, iodine, and oxygen that exhibits significant structural variety.
About CaIO2
CaIO2 is a complex inorganic compound composed of calcium, iodine, and oxygen. As a semiconducting material, it exhibits electronic properties that distinguish it from simple ionic oxides, though its precise role in advanced material systems remains a subject of ongoing investigation.
This compound is characterized by a notable degree of structural diversity, with numerous reported configurations across crystallographic databases. Because it resides above the thermodynamic hull, it is considered a metastable phase, which highlights the synthetic challenges involved in stabilizing this specific stoichiometry.
Key Properties
Cross-validated computational properties for CaIO2, aggregated across 2 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.

How It Compares
As a unique inorganic phase, CaIO2 occupies a distinct niche in materials science where its metastability suggests it may exist as a transient or specialized structure rather than a bulk-stable mineral. Unlike more common, highly stable calcium-based oxides, this compound represents a complex experimental target that requires specific synthesis conditions to isolate.
