Abstract
Before the vaporous and gaseous products are cooled and diluted in the manner specified in the parent Specification, they are cooled to a temperature which is such as to produce a mixture of magnesium, magnesium oxide, and carbon, and after the cooling and dilution the resulting dust is compacted and the magnesium distilled therefrom in an electric resistance furnace. The proportion of magnesium to the other constituents depends upon the exact temperature to which the products are cooled. The mixture is then compacted with hydrocarbon oils, and brought into the form of porous granules by heating to temperatures at which the oils are cracked. The granules are heated by direct resistance heating and the magnesium condensed. In an example, cooling from 1900 DEG C. to 1780 DEG C., which may be effected by adjustment of the furnace temperature or by allowing the temperature of the gaseous products to fall gradually, produces an equimolecular mixture of magnesium and carbon and magnesium oxide.
