Electrolysis of metal oxides in MgCl2 based molten salts with an inert graphite anode [PDF]
Eletrolysis of solid metal oxides has been demonstrated in MgCl2-NaCl-KCl melt at 700 oC taking the electrolysis of Ta2O5 as an example. Both the cathodic and anodic processes have been investigated using cyclic voltammetry, potentiostatic and constant ...

A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.

An investigation on the formation mechanism of nano ZrB2 powder by a magnesiothermic reaction [PDF]
Nanocrystalline zirconium diboride (ZrB2) powder was produced by mechanochemistry from the magnesiothermic reduction in the Mg/ZrO 2/B2O3 system. The use of high-energy milling conditions was essential to induce a mechanically induced self-sustaining ...

Carbothermal reduction of Titanium monoxide (TiO)
The carbothermal reduction of TiO was investigated and compared with that of TiO2 using a thermodynamic approach and experiments. Cubic-TiO powder was synthesized using a high-energy mill to understand the reduction and carburization process. During the reduction and carburization process, TiO is found to be changed into TiC and Ti2O3 simultaneously at

Perovskite‐Type Metal Oxides and the Role of Carbon Materials in Zn‐Based Aqueous Batteries
Carbon materials play a critical role in perovskite‐type metal oxide cathodes for zinc‐based batteries. Beyond improving electrical conductivity, carbon actively participates in oxygen reduction and evolution reactions, forming metal–oxygen carbon bonds that enhance catalytic performance.

Solid State Carbothermal Reduction of Alumina
The Hall-Heroult process, the only commercial technology for aluminum production requires high energy and is a major origin of perfluorocarbons and green house gases. A promising alternative process, carbothermal reduction of alumina to metallic aluminum has advantages of lower capital cost, less energy consumption, and lower emission of green house ...

ABSTRACT Binder jetting has emerged as a compelling approach for processing lunar regolith, as it is well‐suited for low‐energy environments and requires lower amounts of organic binder, compared to the competitive technologies. This study investigates the feasibility of binder jetting lunar regolith simulants from micrometric particles, focusing on ...

Carbothermic Reduction of Alumina: A Thermodynamic Analysis
Abstractusing new thermodynamic data for Al4C3, stability relationships in the Al-C-O system have been determined. A Pourbaix-Ellingham diagram has been constructed and is used to evaluate the equilibrium carbothermic-reduction process. The analysis indicates that liquid Al can never be obtained below 2100° K and that appreciable amounts of Al2O(g) are
