Niobium pentoxide (Nb2O5) is a refractory ceramic oxide semiconductor belonging to the transition metal oxide family, valued for its high melting point, chemical stability, and semiconducting properties. It is primarily used in optical coatings, photocatalytic applications, and as a component in advanced ceramics and glass formulations, where its ability to enhance refractive index and thermal stability makes it preferable to more common alternatives. The material is also gaining traction in emerging applications such as energy storage devices and photocatalytic water treatment, where its semiconducting band structure enables charge carrier separation.
