Refinement of iron ore sinter phases : a silico-ferrite of calcium and aluminium (SFCA) and an Al-free SFC, and the effect on phase quantification by X-ray diffraction

Liles, David C.; De Villiers, J.P.R. (Johan); Kahlenberg, Volker (Springer, 2016-02)

Crystals of a silico-ferrite of calcium and aluminium (SFCA) and an Al-free SFC were prepared from the melt by slow cooling of synthetically prepared mixtures and examined by single-crystal diffraction methods. Both ...
β-alumina-14H and β-alumina-21R : two chromic Na2-δ(Al,Mg,Cr)17O25 polysomes observed in slags from the production of low-carbon ferrochromium

Hejny, Clivia; Kahlenberg, Volker; Schmidmair, Daniela; Tribus, Martina; De Villiers, J.P.R. (Johan) (Elsevier, 2016-09)

The crystal structures of unknown phases found in slags from the production of low-carbon ferrochromium were studied by powder and single-crystal X-ray diffraction. Two phases of Na2−δ (Al, Mg, Cr)17O25 composition were ...
