A containerless study of short-range order in high-temperature Fe-Si-Al-Ca-Mg-Cr-Cu-Ni oxide systems

► A levitated Fe-Si-Al-Ca-Mg-Cr-Cu-Ni oxide system was studied by XRD at 1500 °C. ► Reverse Monte Carlo revealed a network of distorted SiO4 and AlO4 tetrahedra. ► Among Fe and Mg network-modifiers Mg bonded more effectively to silicate bridging O. ► Ca was uncoordinated within the first peak of the total RDF due to Mg competition. ► Cr was coordinated in O tetrahedra without assuming network-forming positions.
