| Popis: |
FeTiO3 and FeTiO3-Fe2O3 solid solution systems were synthesized based on the ceramic method. The synthetic FeTiO3-Fe2O3 solid solutions were subjected to isothermal carbothermal reduction experiments at 1150℃ combining with thermodynamic anal-ysis. The synthetic products were systematically studied by X-ray diffraction and scanning electron microscopy-energy dispersive spec-troscopy. The results show that the synthetic products are all ideal with homogeneous components. From the view of reduction, the smaller the value of x, the molar fraction of FeTiO3, the earlier the carbothermal reduction of xFeTiO3-(1-x)Fe2O3 solid solutions start, and the higher the maximum reduction rate is. As an intermediate phase, pseudobrookite (FeTi2O5-Fe2TiO5 (Fe3Ti3O10)) does not disappear during the whole initial reduction stage until the formation of metal iron (Fe) and ulv-spinel (Fe2TiO4). |
