ceramic

· JVASP-9690· NbPO5

NbPO5 is a niobium phosphate ceramic compound belonging to the phosphate ceramic family, characterized by a layered crystal structure that exhibits relatively low exfoliation energy, making it amenable to mechanical or chemical separation into thin sheets. This material is primarily of research interest for applications requiring high stiffness combined with potential for nanosheet or laminar architectures, with potential use in advanced structural composites, thermal barrier coatings, and solid-state energy storage systems where its chemical stability and mechanical properties can be leveraged.
