Studies on the Thermal Production of Magnesium

The behavior of impurities in the metal

Abstract

The behavior of impurities in magnesium metal produced by the silicothermic process, was described.
At the reduction process, several impurities, such as Fe, Si, Mn, Zn etc., were contained in the deposit metal. Distribution of each element in the deposit was explained. It was found that some parts of manganese and zinc contained in raw materials are distilled, that is, about 2% of Mn and 70% of Zn are included in the deposit.
At the melting process, it was found that the iron crusible and the flux for melting of deposit don'tcontaminate the molten magnesium.
By the distillation through the wire netting filters placed at the hot end of the condenser, high purity magnesium was produced, and its purity was more than 99.98%
