· JVASP-19102· Ca3Ti2O7

Calcium titanate (Ca₃Ti₂O₇) is a ceramic compound belonging to the perovskite-related oxide family, characterized by a layered crystal structure that combines calcium and titanium oxides. This material is primarily studied for advanced applications requiring thermal stability and dielectric properties, including microwave-frequency components, thermal barrier coatings, and electroceramics; it is less commonly used in high-volume commercial production compared to simpler titanates, making it valuable for specialized engineering environments where its particular crystal structure and thermal characteristics provide advantages over conventional alternatives.
