Slag-containing pastes and concretes were analysed by element-specific synchrotron-based techniques to determine the speciation of iron on crushed materials through spatially resolved micro-spectroscopic studies. The investigated cement samples hydrated either in laboratory, or exposed river sea water. Metallic iron, along with minor proportions sulphide magnetite was detected laboratory sample...

Cation ordering in solids is important for controlling physical properties and leads to ilmenite (FeTiO3) LiNbO3 type derivatives of the corundum structure, with ferroelectricity resulting from breaking inversion symmetry latter. However, a hypothetical third ABO3 derivative R32 has never been observed. Here we show that Co2InSbO6 recovered high pressure new, ordered-R32 A2BCO6 variant structur...

We present a model for the lattice vibrational density of states MgTiO3 (geikielite) and FeTiO3 (ilmenite) that predicts thermodynamic properties, in agreement with observational data. The is based on Kieffer’s method combined spectroscopic For both substances experimental data sets are influenced by non-stoichiometry. geikielite affects volume, whereas ilmenite volume bulk modulus affected. sh...

This article aimed to separate ilmenite (FeTiO3) mineral from tin tailing applying a single splitter IRMS (Induced Roll Magnetic Separator). Ilmenite is the substantial main source for TiO2. work used air table middling feeding. The components of feeding using grain counting analysis were found as follows: cassiterite (48.61%), (21.36%), monazite (18.56%), pyrite (4.60%), zircon (5.85%), quartz...

Metal-metal charge transfer (MMCT) is expected to be the main mechanism that enables the harvesting of solar light by iron-titanium oxides for photocatalysis. We have studied FeTiO3 as a model compound for MMCT with 1s2pRIXS at the Fe K-edge. The high-energy resolution XANES enables distinguishing five pre-edge features. The three first well distinct RIXS features are assigned to electric quadr...

Seven ilmenite (FeTiO3) megacrysts derived from alnöite pipes (Island of Malaita, Solomon Islands) were characterised for their major and trace element compositions in relation to their potential use as secondary reference materials for in situ microanalysis. Abundances of thirteen trace elements obtained by laser ablation ICP-MS analyses (using the NIST SRM 610 glass reference material) were c...
