Abstract: The reaction kinetics of preparation of vanadium-aluminum alloy by thermite method was studied by DSC.Reaction activation energy was obtained by Flynn-Wall-Ozawa equation,and Kissinger equation was used to verify the reliability of the calculated reaction activation energy by Flynn-Wall-Ozawa equation,showing an almost consistent value for both of the methods. Other kinetics parameters were obtained to establish the kinetics equation for the thermite reaction by Kissinger-Crane equation using the average value of activation energy calculated by Flynn-Wall-Ozawa and Kissinger equation as input parameter.The results show that the average apparent activation energy,reaction order and frequency factor for the reaction of vanadium-aluminum alloy preparation by thermite method is 386.5 kJ · mol^-1,1.04 and 3.361×10³⁰min^-1,respectively.
