Perovskite · Calcium titanate
Calcium titanate is a thermodynamically stable, insulating oxide that defines the structural characteristics of the perovskite mineral group.
About Perovskite
Calcium titanate is a quintessential perovskite oxide that serves as the namesake for the entire structural class. It is characterized by its robust thermodynamic stability and insulating electronic nature, making it a foundational material in solid-state chemistry research. Its structural versatility is evidenced by the numerous reported configurations found across major materials databases. Because of its structural integrity and chemical resilience, it remains a primary subject for studying phase transitions and crystal chemistry in oxide systems. It is frequently utilized as a substrate or a precursor in the synthesis of complex functional ceramics and electronic components.
Key Properties
Cross-validated computational properties for Perovskite, aggregated across 4 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.
While compounds like BaTiO3 are widely recognized for their prominent ferroelectric properties, CaTiO3 is distinguished by its structural stability and role as a prototypical perovskite. Unlike the more electronically active or magnetic members of the class such as LaMnO3 or LaCoO3, calcium titanate functions primarily as a stable, wide-gap insulator that provides a reliable structural framework for doping and heterostructure engineering.
