La2TiO5
La2TiO5 is a stable, insulating perovskite oxide used in materials science research for its structural reliability and electronic properties.
About La2TiO5
La2TiO5 is a structurally robust perovskite oxide that exists as a thermodynamically stable phase. Characterized by its wide-band-gap insulating nature, this compound represents a key material in the study of lanthanum-based titanates where electronic insulation is a primary requirement. Its stability on the convex hull makes it a reliable candidate for high-temperature applications and specialized ceramic components. The material is valued for its structural integrity and its ability to maintain phase stability under varying environmental conditions, contributing to its utility in advanced oxide electronics and dielectric research. It serves as a foundational material for exploring the interplay between rare-earth elements and transition metal oxides.
Key Properties
Cross-validated computational properties for La2TiO5, 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 perovskite oxides class.
Unlike the metallic or semi-metallic behavior often seen in siblings like LaNiO3, La2TiO5 is a distinct insulator. While materials such as BaTiO3 are widely utilized for their ferroelectric properties, La2TiO5 occupies a niche as a stable, wide-gap oxide that provides a different electronic profile compared to the magnetic transition metal perovskites like LaMnO3 or LaFeO3.
