· Na2Ti2O5

Na2Ti2O5 is a sodium titanate ceramic compound belonging to the layered titanate family, characterized by a mixed-valence titanium oxide structure with alkali metal incorporation. While primarily a research compound rather than a commercial material, sodium titanates are investigated for applications requiring ion-exchange properties, photocatalytic activity, and thermal stability, making them candidates for advanced ceramic applications where conventional oxides fall short. Engineers typically evaluate this material class for niche applications in environmental remediation, energy storage, and photocatalytic systems where the combination of titanium oxide functionality and ion-exchange capability offers distinct advantages over single-phase alternatives.
