Abstract Scope |
The majority of pure magnesium produced worldwide are made by using Silicothermic method (Pidgeon process). However, the Pidgeon process suffers poor efficiency, low industrial concentration and intermittent production. The main reason is that Pidgeon process requires to keep the reaction chamber in vacuum state during the entire reduction process. By analyzing the thermodynamic reaction principle, we reveal that it is the low magnesium partial pressure instead of vacuum that is necessary for the Silicothermic process. Based on this understanding, we develop a new technique that can produce pure magnesium under the atmospheric pressure by using silicothermic method. The magnesium production efficiency of this new technique is comparable to the widely used Pidgeon method. The industrialized application of this exciting technique is expected to help the Silicothermic to realize high efficiency, automated and continuous production while at the same time completely change the poor production conditions, reduce energy consumption and pollution. |
