Carbothermic Reduction of Alumina: A Thermodynamic Analysis
Canadian Metallurgical Quarterly, 1965 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

Stepwise carbothermal reduction of bauxite ores
International Journal of Mineral Processing, 2013 Abstract The commercial technologies for aluminium production include production of alumina from bauxite and smelting of alumina to produce aluminium. The current technology is energy intensive, and a major source of greenhouse gas emissions and harmful fluoride emissions.

Environmental Toxicology, EarlyView.ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have
