Used as a catalyst in organic synthesis reactions, particularly in acid-catalyzed processes such as esterification and dehydration. Exhibits good thermal stability, making it suitable for high-temperature catalytic applications.

Employed in the production of advanced ceramics and electronic materials due to its ability to form niobium-based oxides with desirable dielectric properties. Also noted for corrosion resistance, making it suitable for components in harsh environments like engines or industrial furnaces.

Investigated for use in electrochemical devices, including capacitors and sensors, because of its ion-exchange capabilities and surface reactivity.

Also serves as a precursor in the synthesis of niobium pentoxide, which is important in optical coatings and lithium-ion battery materials. Studied in energy research for electrodes in batteries or supercapacitors due to efficient charge storage and release.
