ThI4
Thorium tetraiodide is a stable semiconducting compound of thorium and iodine used in chemical synthesis and metallurgical processes.
About ThI4
Thorium tetraiodide is a thermodynamically stable inorganic compound that exists on the convex hull, indicating significant structural robustness. As a semiconducting material, it exhibits distinct electronic properties that differentiate it from more common ionic halides. Its presence across multiple databases highlights its importance in fundamental materials research and specialized chemical synthesis. The compound is primarily utilized in high-temperature processes and as a precursor in the production of high-purity thorium metal. Its stability makes it a reliable subject for studying actinide-halogen bonding and coordination chemistry in solid-state systems.
Key Properties
Cross-validated computational properties for ThI4, 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.
