· JVASP-12079· Te4O9

Te4O9 is a tellurium oxide ceramic compound with a layered crystal structure, belonging to the family of transition metal and post-transition metal oxides. This material is primarily of research interest rather than established industrial production, with potential applications in optoelectronic devices, solid-state ionics, and catalytic systems where tellurium oxides have shown promise due to their mixed-valence electronic properties and anisotropic crystal structures.
