Li8SiO6
Li8SiO6 is a stable, insulating lithium silicate oxide used primarily in fundamental materials research.
About Li8SiO6
Li8SiO6 is a lithium-rich oxide that functions as a wide-band-gap insulator. As a thermodynamically stable phase residing on the convex hull, it represents a robust crystalline arrangement within the lithium-silicon-oxygen system.
This compound is of significant interest in materials science due to its unique stoichiometry and structural stability. Its insulating nature and chemical composition make it a subject of study for potential applications in solid-state ionics and advanced battery electrolyte research.
Key Properties
Cross-validated computational properties for Li8SiO6, 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.

How It Compares
Within the lithium oxides class.
Unlike the transition-metal-based oxides in its class such as LiCoO2, LiMn2O4, or LiNiO2, which are primarily valued for their redox-active metal centers in cathode applications, Li8SiO6 serves as a stable, insulating structural framework. It shares more functional similarities with Li4SiO4 as a silicate-based lithium compound, contrasting with the more conductive or electrochemically active members of the lithium oxide family.
