• The identification procedure showed no significant differences in qualitative phase composition of the examined sinters. There were only small discrepancies in occurrence of some silicate components (as e.g. magnesium silicate), but their contents were about 1 wt.%, so their influence on properties of the

• There is a clear dependence between static susceptibility to degradation RDI-1-3.15 and quantities of mineral components of the sinters. This is not observed for all minerals - amorphous component do not show any kind of correlation with values of RDI-1-3.15. The correlation of the content of hematite
