· JVASP-52566· TiGa2O5

TiGa₂O₅ is a titanium gallium oxide ceramic compound belonging to the mixed-metal oxide family, combining titanium and gallium cations in a stabilized crystalline structure. This material is primarily of research interest for semiconductor and photocatalytic applications, where the mixed-oxide composition can offer tunable electronic properties and potential activity under visible light compared to single-component titanium oxide ceramics. While not yet widely deployed in high-volume industrial production, materials in this family are being investigated for photocatalysis, gas sensing, and optoelectronic device applications where the gallium dopant modifies band structure and surface reactivity.
