摘要
Fe-57 Mossbauer spectra were recorded at room temperature of six quenched slags in the system FeO-Fe2O3-CaO-Al2O3-SiO2 at depths of 10 mum, 250 mum and 1000 mum from the surface. The Fe3+ composition decreases as a function of depth in CaO-containing slags, while it increases with depth when no CaO is present. The mean isomer shift of Fe2+ is essentially constant with both bulk composition and depth, while the mean Fe2+ quadrupole splitting increases substantially with bulk iron content and shows large depth dependence in slags synthesized at Fe saturation.
