· JVASP-49788· K4TiO4

K₄TiO₄ is a potassium titanate ceramic compound belonging to the family of layered titanate materials, which are characterized by sheet-like crystal structures and ion-exchange properties. This material is primarily investigated in research contexts for advanced ceramic applications, particularly where ion-exchange capabilities, thermal stability, and potential photocatalytic or ion-conduction behavior are valuable; it is less commonly used in high-volume industrial production compared to conventional titanates, making it relevant for engineers developing next-generation functional ceramics rather than established commodity applications.
