In this study, it is aimed to assess the feasibility of converting vanadium pentoxide into vanadium metal via hydrogen reduction. To achieve this, V 2 O 5 powder is pressed into a cylindrical shape and subjected to a reduction in a high‐temperature microscope under a constant hydrogen flow rate of 0.5 L min −1 , within a temperature range of 600–1400 °C. The experimental results are complemented by thermodynamic calculations using FactSage 7.2. The microstructure and composition of the samples are analyzed using scanning electron microscopy with energy‐dispersive X‐ray spectroscopy and X‐ray diffraction analyses. Subsequent to the experiment, only V 2 O 3 and VO are identified in the samples, and no metallic vanadium is observed.
