摘 要：<正> The mechanism and influence factors of thermal decomposition of NH4VO3 in Ar to produce V6O13were investigated by TG-DTG, DSC, X-ray diffraction and orthogonal design experiments at 25～450℃.Theprocess includes four reactions, among which the reduction of V2O5 by NH3 is one of the most importantstagrt controlling the constituents of the fina1 products, and it is affected by heating rate and amount ofNH4VO3 singnificantly. This reduction reaction is controlled by a first order reaction or nucleation and nucleigrowth with a kinetic equation--ln（l-a）=kt,and apparent activation energy of 410kJ/molis obtained.
