About KSO4
KSO4 is an insulating compound characterized by a wide electronic band gap. As a metastable material, it represents a unique structural configuration that challenges conventional thermodynamic stability expectations within its chemical system.
Its existence across multiple structural databases highlights its significance as a subject of ongoing crystallographic study. Researchers investigate this compound to better understand the phase behavior and structural diversity of potassium-sulfur-oxygen systems.
Key Properties
Cross-validated computational properties for KSO4, 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.
