Effects of mineralogical composition into the reactivity of calcinated ilmenite for chemical looping technologies

Journal of Materials Research and Technology
Ilmenite is one of the most promising oxygen carriers (OC) for chemical looping combustion (CLC) on a large scale. However, ilmenite samples from distinct mines submitted to diverse mineral processing procedures do not have homogeneous physicochemical ...

Quantitative Evaluation of Shock Metamorphism in Clinopyroxene Using In Situ X‐Ray Diffraction Measurement of Lattice Strain

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Shock metamorphism is a ubiquitous process in our solar system. Shock pressure can be related to the lattice strain (ε) of individual minerals within a shocked sample. The lattice strain can be quantified within intact samples by in situ micro‐X‐ray diffraction (μXRD) using the Williamson‐Hall method. The Williamson‐Hall lattice strain (W‐H ε)

Thermodynamic Justification for the Effectiveness of the Oxidation—Soda Conversion of Ilmenite Concentrates

Processes
This article presents the results of a thermodynamic analysis of the oxidation soda conversion reactions of minerals in ilmenite concentrates in the temperature range of 373–2273 K. The thermodynamic parameters of pseudorutile, pseudobrukite, and the new minerals, zhikinite and spessartine, were calculated for the first time.
