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.
