Ti11O18

Ti11O18 is a titanium oxide ceramic compound belonging to the Magnéli phase family of reduced titanium oxides, characterized by a crystalline structure intermediate between TiO2 and lower oxidation states. This material is primarily investigated in research and specialized applications where its unique electrical and optical properties—stemming from mixed-valence titanium—offer advantages over conventional rutile or anatase phases; industrial use remains limited, with most development focused on electrochemical devices, photocatalysis, and high-temperature structural applications where its reduced band gap and electron conductivity are exploited.
