A Mossbauer study of electric steelmaking basic slags

Mössbauer measurements have been made on powder samples of basic slags from a steelmaking electric furnace. The samples were taken during oxygen blowing. A prevalence is found of divalent iron in “mixed oxidrd form and in the silicate phase. The ability of Mössbauer spectroscopy to characterize such heterogeneous materials and to correlate the distribution of ferrous ions between the oxide and the silicate with the composition of the slags is demonstrated.
