| Abstract Scope |
Using biomass glucose as carbon source, vanadic titanomagnetite (VTM) was carbon coated by hydrothermal carbonization, and carbon-coated vanadic titanomagnetite (CCVTM) was obtained. The reduction behaviors of the CCVTM and VTM at different temperatures were systematically studied. The phase, microstructure, and surface composition of the reduction products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and Energy Dispersive Spectrometer (EDS). The results show that the surface of CCVTM is covered by 0.3 μm~1 μm carbon spheres. After reduction at 1100℃ for 120min, the coated carbon spheres still exist, indicating that the carbon spheres have high stability. Iron whisker appeared in the reduction products after reduction of VTM at 800℃ for 120min. There is no iron whisker in the reduction samples of CCVTM at 700℃ ~ 1200℃ for 120min. Carbon coating can inhibit the formation of iron whisker during the reduction process. |
