About antimony trichloride
Antimony trichloride is a thermodynamically stable compound that functions as a wide-gap insulator. Its distinct chemical properties make it a versatile reagent in laboratory settings and industrial manufacturing processes.
Because it resides on the convex hull, this material exhibits robust stability under standard conditions. It is frequently employed as a precursor for other antimony-containing materials and plays a significant role in specialized chemical synthesis.
Key Properties
Cross-validated computational properties for antimony trichloride, 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.
