About dysprosium orthophosphate
Dysprosium orthophosphate is a robust, thermodynamically stable inorganic compound characterized by its insulating electronic nature. As a member of the rare-earth phosphate family, it exhibits high structural integrity, making it a reliable candidate for specialized ceramic and optical applications.
Its stability on the convex hull underscores its potential for long-term performance in demanding environments. Researchers value this material for its predictable behavior and the unique magnetic contributions provided by the dysprosium cation within the phosphate framework.
Key Properties
Cross-validated computational properties for dysprosium orthophosphate, aggregated across 2 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.
