摘要： The present disclosure provides a method for partially reducing vanadium pentoxide (V2O5) using an ammonia solution, wherein ammonia is used to convert vanadium pentoxide (V2O5) powder to ammonia vanadate (NH4VO3), which is an intermediate material, after which the ammonia vanadate is heated under normal or reduced pressure in a nitrogen or argon atmosphere and then maintained for a certain period of time to partially reduce the vanadium pentoxide and thereby produce vanadium dioxide (VO2) powder; and vanadium dioxide (VO2) powder produced thereby.

摘要： This production method includes: an alkali extraction step (step 12) of adding an alkali and water, or an alkali solution, to raw material ash containing an ammonium sulfate component, sulfuric acid, vanadium, and at least one other metal selected from nickel, iron, and magnesium, such that a pH of 13 or higher is achieved, to obtain an alkali leachate; a solid-liquid separation step (step 13) of performing solid-liquid separation on the alkali leachate to obtain a leach filtrate containing vanadium; an evaporation concentration step (step 14) of evaporating and concentrating the leach filtrate to obtain a concentrated liquid; and a crystallization/solid-liquid separation step (step 15) of cooling and crystalizing the concentrated liquid and recovering a precipitate containing a vanadium compound. Another production method includes an alkali extraction step (step 32), a solid-liquid separation step (step 4), an evaporation concentration step (step 36), an alkali concentration adjustment step (step 37) of further adding an alkali or an alkali solution to a concentrated liquid to obtain a concentration-adjusted liquid, and a crystallization/solid-liquid separation step (step 38).
