Abstract：The effects of milling time on the reduction process of TiO₂-V₂O₅-C mixtures were investigated using SEM, TG-DSC, X-ray diffraction and particle size analysis. Results show that the mean particle size of milled mixtures increases slightly due to agglomeration with increasing milling time. When the milling time increases from 8 h to 24 h, the mass loss curves shift to lower temperatures, indicating that the reduction process is accelerated.When the milling time is further increased to 24 h, the change of mass loss and endothermic peaks varys little. When the milling time is 16 h, deoxidization gradually occurrs and Ti_0.8V_0.2C forms.
