· Ca2 Ti4 O8

Ca₂Ti₄O₈ is a calcium titanate ceramic compound that belongs to the titanate family of mixed-metal oxides, typically investigated as a semiconductor material with potential photocatalytic or electronic applications. This compound exists primarily in research and development contexts rather than as an established commercial material, with exploration focused on photocatalysis, photoelectrochemistry, and potential optoelectronic device applications where titanate-based semiconductors show promise. Its layered perovskite-related structure and tunable bandgap position it as a candidate material for solar-driven catalytic processes and advanced ceramics, though widespread industrial adoption remains limited compared to more established titanates like TiO₂ and strontium titanates.
