Silver perchlorate · Perchloric acid silver salt
Silver perchlorate is an insulating, stable inorganic salt primarily used as a versatile reagent in chemical synthesis and laboratory applications.
About Silver perchlorate
Silver perchlorate is a well-characterized inorganic compound that exists as a thermodynamically stable phase. Its electronic structure is defined by a wide band gap, classifying it as an insulator under standard conditions.
Due to its high solubility and reactivity, it serves as a critical reagent in organic and inorganic synthesis. It is frequently employed in laboratories to facilitate the precipitation of halides or to act as a source of silver ions in complex chemical transformations.
Key Properties
Cross-validated computational properties for Silver perchlorate, 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.
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.
