WebCorrect option is D) Very high temperatures around 2100 degree celcius is required for the carbothermic reduction. Aluminium Oxide is a very stable oxide and lies below the the oxidation line of carbon in Ellingham Diagram hence Al 2O 3 cannot be reduced by carbon as it is energetically not favourable. Hence option D is correct answer. WebJun 28, 2024 · 2. Generally speaking, manufacturers remove oxygen from metal by using deoxidizers. For instance, a manufacturer will melt steel, and pour liquid aluminum (or various other viable substances that act as reducing agents) into the liquid steel. This aluminum will react with the oxygen in the steel to form aluminum oxide (Al2O3). takamine gn20ce-ns https://caminorealrecoverycenter.com
