Lead titanate · PbTiO3
Lead titanate is a stable, semiconducting perovskite oxide widely utilized in the manufacturing of high-performance electronic and piezoelectric devices.
About Lead titanate
Lead titanate is a prominent member of the perovskite oxide family, characterized by its robust thermodynamic stability. As a semiconducting material, it serves as a foundational building block for functional ceramics and electronic devices that rely on precise structural integrity.
Its significance stems from its versatile crystal structure, which has been extensively documented across multiple databases. This reliability makes it a preferred choice for applications requiring consistent material performance in demanding technological environments.
Key Properties
Cross-validated computational properties for Lead titanate, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
