K2Ti2O5
K2Ti2O5 is a thermodynamically stable, wide-band-gap insulating oxide belonging to the perovskite family.
About K2Ti2O5
K2Ti2O5 is a structurally robust perovskite oxide that maintains thermodynamic stability on the convex hull. As a wide-band-gap insulator, it possesses electronic characteristics that distinguish it from the more conductive or magnetic members of the perovskite family, making it an intriguing candidate for specialized dielectric applications.
This compound is valued for its structural integrity, supported by multiple documented crystal structures across scientific databases. Its role as a stable oxide positions it as a foundational material for exploring chemical substitutions and structural variations within the broader perovskite framework.
Key Properties
Cross-validated computational properties for K2Ti2O5, aggregated across 3 databases.
