WebVanadium pentoxide (V 2 O 5) is perhaps vanadium's most useful compound. It is used as a mordant, a material which permanently fixes dyes to fabrics. Vanadium pentoxide is also used as a catalyst in certain chemical reactions and in the manufacture of ceramics. Vanadium pentoxide can also be mixed with gallium to form superconductive magnets. WebVanadium pentoxide is a commercially important catalyst for the production of sulfuric acid, a reaction that exploits the ability of vanadium oxides to undergo redox reactions. [18] The vanadium redox battery utilizes all four oxidation states: one electrode uses the +5/+4 couple and the other uses the +3/+2 couple.
WebThis includes the production of high purity vanadium pentoxide using hydrometallurgical methods, tested as part of the detailed flowsheet validation program undertaken by the Company and its consultants since the 2024 Pre-Feasibility Study (PFS)1 and following up successfully on previous vanadium pentoxide results2. Vanadium(V) oxide is produced when vanadium metal is heated with excess oxygen, but this product is contaminated with other, lower oxides.
