· JVASP-9459· Ca2Ti3O8

Ca₂Ti₃O₈ is a calcium titanate ceramic compound belonging to the perovskite-related oxide family, characterized by a layered crystal structure that combines calcium and titanium cations with oxygen anions. This material is primarily investigated in research and specialized applications for its refractory properties, dielectric characteristics, and thermal stability, making it relevant to high-temperature engineering environments where conventional ceramics may degrade. Its potential applications span advanced refractories, thermal barrier coatings, and electrical ceramics, though it remains less established in mainstream industry compared to widely-adopted titanate compounds like CaTiO₃.
