Abstract: Temperature is an important factor to affect the diffusion coefficient and the reaction rate.The experimental study on the variation of reduction process of vanadium titanium magnetite at the same time and different temperatures was performed, and the reduction mechanism of vanadium-titanium magnetite by microwave carbon-thermal was explored.The results showed the conditions of mass transfer and the reduction effects of can be significantly improved at 1 400~ 1 500 ℃, thus achieving vanadium alloy by removing iron slag.
