LiNb3O8 is a thermodynamically stable lithium-niobium oxide that acts as an electrical insulator.
About LiNb3O8
LiNb3O8 is a thermodynamically stable lithium oxide that functions as a wide-band-gap insulator. As a member of the lithium oxide family, it exhibits structural characteristics typical of complex ternary oxides, maintaining a robust lattice arrangement that sits on the convex hull of stability. Its electronic properties make it a subject of interest for fundamental materials research into insulating ceramic systems.
This compound is primarily utilized in specialized materials science applications where stable, non-conductive lithium-containing phases are required. Its structural integrity and chemical composition allow it to serve as a reliable model system for studying phase stability and ion transport in complex oxide environments.
Key Properties
Cross-validated computational properties for LiNb3O8, 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.

How It Compares
Within the lithium oxides class.
Unlike the highly active cathode materials LiNiO2, LiMn2O4, and LiCoO2, which are prized for their electrochemical redox capabilities, LiNb3O8 is characterized by its insulating nature and structural stability. While it shares the lithium-oxide classification with materials like Li2O or Li2TiO3, it occupies a distinct niche as a stable, wide-gap dielectric rather than an active electrode component.
