Ge4K4O14Zr2 is a thermodynamically stable, insulating quaternary oxide composed of germanium, potassium, oxygen, and zirconium.
About Ge4K4O14Zr2
Ge4K4O14Zr2 is a complex oxide featuring germanium, potassium, and zirconium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these elements that resists decomposition under standard conditions.
This material functions as a wide-gap insulator, a characteristic that makes it a subject of interest for fundamental studies in solid-state chemistry. Its unique combination of elements suggests potential utility in specialized dielectric or ceramic applications where insulating behavior is required.
Key Properties
Cross-validated computational properties for Ge4K4O14Zr2, aggregated across 3 databases.
