Abstract:
Characterization of variability of the phase composition, chemical composition of individual phases and basic physical properties of iron slags, obtained during the experinmental smelting conducted by the Technical museum in Brno in 2012, has been carried out in this study. Methods of polarized light microscopy and electron microprobe have been used to analyze the phase composition of slags. Five macroscopically different slags have been chosen for a detailed analysis. The composition of slags is considerably heterogeneous. Major phases are olivine, glass and wüstite but their contents in the individual slag samples are very different. Olivines are almost pure fayalites and their chemical composition is almost identical in comparison with historical slags from various locations. The chemical composition of the glass phase is very heterogeneous, major components are SiO2 , FeO, Al2O3 , CaO and K2O. The chemical composition of spinelide has been analysed in one of the slags. It has been proved that it is magnetite containing 24 mol. % of hercynite.
