Influence of FeO/SiO2 and CaO/SiO2 Ratios in Iron ,

Jun 30, 2016· There is no obvious relationship between the amount of olivine and the FeO/SiO 2 ratio or CaO/SiO 2 ratio In comparison, the formation of (Zn,Fe,Mg)O solid solution is enhanced by increasing the FeO/SiO 2 ratio or CaO/SiO 2 ratio in ZFS slags The results suggest that MgO corrosion is the lowest for FeO/SiO 2 and CaO/SiO 2 ratios around 17 .
