ceramic

· JVASP-26716· Na4Ti5O12

Na4Ti5O12 is a sodium titanate ceramic compound that belongs to the titanate family of materials, characterized by a layered crystalline structure combining sodium, titanium, and oxygen. This material is primarily investigated in research contexts for energy storage and ion-exchange applications, particularly as a potential anode material in sodium-ion batteries and as an adsorbent for radioactive ion removal in nuclear waste treatment. Its appeal lies in its ability to reversibly intercalate sodium ions, making it a candidate for next-generation battery technologies where sodium represents a more abundant and cost-effective alternative to lithium.
