Preparation of Mono-, Di- and Hemicalcium Ferrite Phases via Melt for Reduction Kinetics Investigations.

The article presents a study which evaluates the possible production of mono-, di- and hemicalcium ferrite phases via melt for reduction kinetics investigations. Scanning electron microscopy (SEM-EDS) and x-ray diffraction (XRD) were used to identify mineral compositions of calcium ferrite samples. Results of the study indicate the possible production of the samples of calcium ferrites via melting, in which thermodynamic calculations were used to estimate conditions needed for calcium ferrites.
