· V7 O3

V₂O₃ is a vanadium oxide ceramic compound belonging to the transition metal oxide family, known for its semiconducting properties and ability to undergo metal-insulator transitions. It is primarily investigated in research contexts for smart window coatings, thermal sensors, and electronic devices that exploit its temperature-dependent conductivity changes. In industrial applications, vanadium oxides are valued for their catalytic properties in chemical processing and their potential in energy storage systems, though V₂O₃ specifically remains more common in specialized academic and advanced materials development rather than mainstream manufacturing.
