Study on Smelting Metallic Magnesium by Siliconthermic Reducing Method and its Reaction Kinetics

Abstract:

Article Preview

The metallic magnesium by siliconthermic reducing method was studied by magnetite as raw materials. The Mg reduction rate, such as reduction temperature and time, Si-Fe added mount, mineralize CaF2 added, briquette pressure, were discussed by experiments. Through siliconthermic reducing process analyzed, the result showed reduction process was in line with three-dimensional phase boundary reaction D3 model and kinetic equitation were expressed as , with an apparent activation energy 313.58 KJ/mol, frequency factor 2.7×106 s-1.
