Structural elucidation of triclinic and monoclinic SFCA-III - killing two birds with one stone.

ABSTRACT: A part of the system CaO-SiO₂-Al₂O₃-Fe₂O₃-MgO which is of relevance to iron-ore sintering has been studied in detail. For a bulk composition corresponding to 10.45 wt% CaO, 5.49 wt% MgO, 69.15 wt% Fe₂O₃, 13.37 wt% Al₂O₃ and 1.55 wt% SiO₂ synthesis runs have been performed in air in the range between 1100 and 1300°C. Products have been characterized using reflected-light microscopy, electron microprobe analysis and diffraction techniques. At 1250°C, an almost phase-pure material with composition Ca_2.99Mg_2.67Fe³⁺_14.58Fe²⁺_0.77Al_4.56Si_0.43O₃₆ has been obtained. The compound corresponds to
