A MANUFACTURING METHOD OF VANADIUM DIOXIDE

摘要

PURPOSE: A producing method of vanadium dioxide for obtaining a thermochromic material is provided to economically produce the vanadium dioxide using a reducing process and a ball-milling process. CONSTITUTION: A producing method of vanadium dioxide comprises the following steps: preparing beginning powder formed with vanadium pentoxide and tungsten compounds(S110); reducing the beginning powder for 1~5hours at 400~600deg C(S120); adding an additive into the reduced beginning powder, and uniformly mixing by ball-milling; reducing the ball-milled particles for 1~5hours at 300~600deg C(S140); and heat-processing the reduced particles for stabilizing(S150).
