About tripotassium phosphate
Tripotassium phosphate is a highly stable, wide-band-gap insulating compound that exists as a robust crystalline solid. Its thermodynamic stability ensures it remains a reliable choice for chemical processes where consistent performance is required under various environmental conditions. The material is frequently utilized for its ability to regulate acidity and its effectiveness as a source of potassium and phosphorus. It plays a critical role in industrial applications ranging from food manufacturing to specialized chemical synthesis.
Key Properties
Cross-validated computational properties for tripotassium phosphate, 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.
