· Ho2 V2 O7

Ho₂V₂O₇ is a holmium vanadium oxide ceramic compound belonging to the pyrovskite or related oxide semiconductor family. This material is primarily of research interest for applications requiring mixed-valence transition metal oxides, particularly where rare-earth doping and vanadium oxidation states can be engineered to modulate electronic and ionic properties. Industrial adoption remains limited, with most development occurring in academic settings exploring energy storage, catalysis, and solid-state ionic conductivity.
