Cobalt Deposition from Ionothermally Dissolved Cobalt Oxides
ChemSusChem, Volume 16, Issue 9, May 5, 2023., 2023 The cobalt oxides CoO, Co3O4 and LiCoO2 are dissolved in the ionic liquid [Hbet][NTf2], whereupon cobalt can directly be electrodeposited. A special focus is on understanding the complex equilibria present in solution and ways to manipulate them specifically.

Strontium Extraction by Aluminothermic Reduction
Canadian Metallurgical Quarterly, 1991 AbstractExperiments are performed in a mechanically agitated molten bath of aluminium to extract strontium from strontium carbonate by aluminothermic reduction. The molten aluminium contains additions of magnesium or bismuth. Magnesium is added to the melt for two reasons: to increase the reactivity and to lower the surface tension of the molten alloy.
