Magnesium ferrite is a kind of main bonding phase in magnesia refractory materials.Using the powder mixture of active magnesia and chemical reagent Fe2O3 as starting raw materials,DSC experiments of the synthesis reaction of magnesium ferrite were conducted respectively at scanning rates of 10,15,20 K·min-1 in static air.The kinetic parameters of the synthesis reaction of magnesium ferrite were calculated by the Kissinger equation,the Flynn-Wall-Ozawa equation and the Achar-Brindley-Sharp-Wendworth equation.The results show that the formation mechanism of magnesium ferrite obeys the random nucleation and rapid growth model,and the activation energy of the reaction is between 626.83 and 652.60 kJ·mol-1.
