- W1977842029 abstract "Cooling of solidified titania slag in air results in the oxidation of a pseudobrookite phase (M3O5 where M = Fe, Ti) to form phases that are associated with the disintegration of the solid slag. Extensive disintegration of the slag at temperatures below 773 K is accompanied by the formation of a disordered MOx phase, which is a unit cell intergrowth of anatase (TiO2), and M3O5 structural elements. In situ X-ray diffraction measurement and Rietveld refinement of the pseudobrookite unit cell parameters yielded values for spontaneous strain associated with the oxidation of the slag. In the most reactive samples oxidised isothermally at 473 K there is 0·6% contraction along the a-axis, a 0·3% expansion along the b-axis and the c-axis expands by 1%, while still retaining the pseudobrookite structure. Values for the elastic constants and Young's moduli for M3O5 were calculated using the GULP crystal optimisation code. These values, together with experimental values for the spontaneous strain tensor and the fracture toughness of M3O5, were used to calculate the critical crack size for crack propagation. Crack sizes of 0·9–9 μm are sufficiently large to explain the cracking that preceded the extensive formation of MOx and the subsequent segmentation of the solid slag into very small particle sizes. Lattice energy calculations of the compounds anatase (TiO2), FeTi2O5, and FeTi5O11 with GULP showed that the latter is unstable by 173 kJ mole−1 as compared to a mixture of anatase (TiO2) and FeTi2O5 and will eventually revert to anatase (TiO2) and M3O5." @default.
