Calcium titanium phosphate (Ca₂Ti₂P₂O₁₀) is an inorganic ceramic compound belonging to the phosphate family of semiconductors, combining calcium, titanium, and phosphate elements in a structured crystalline lattice. This material is primarily investigated in research contexts for photocatalytic and photovoltaic applications, where its semiconductor properties enable light-driven chemical reactions and potential energy conversion; it is also explored for biomedical applications such as bone scaffolding and bioactive coatings due to the biocompatibility of its constituent elements. Engineers would consider this material for advanced applications requiring combined mechanical rigidity, chemical stability, and semiconductor functionality, though it remains largely in the development stage compared to established alternatives like titania (TiO₂) or hydroxyapatite-based ceramics.
