Strontium zirconate is a stable, insulating perovskite oxide used in electronic components and high-temperature materials science.
About Strontium zirconate
Strontium zirconate is a prominent member of the perovskite oxide family, characterized by its robust thermodynamic stability and insulating electronic nature. Its structural integrity and chemical resilience make it a versatile candidate for high-temperature applications and as a dielectric component in advanced electronic devices.
Beyond its structural utility, this compound is highly regarded for its potential in oxygen-ion conduction and as a substrate material. Its ability to maintain stable phases across various conditions allows it to function effectively in demanding environments where other oxides might degrade.
Key Properties
Cross-validated computational properties for Strontium zirconate, 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.
