Abstract
Magnesium and high-percentage magnesium alloys are refined by melting them with a halide or sulphide of a heavy metal selected from the group I, II, V, VI, VII, and VIII of the periodic system, such metals, base metals excepted, being chosen which have a specific gravity above 6 and below 11. Magnesium halides may be used in addition to the halides or sulphides referred to. The salts or mixtures of salts must be such as have melting points below that of magnesium and a specific gravity higher than that of the molten magnesium. The salts &c. may be melted, solidified, and the fused mass crushed before use. In one example, magnesium refined by distillation was melted with a mixture of equal parts of zinc chloride, ferric chloride, and magnesium chloride. In another example, a magnesium alloy containing 4 per cent of aluminium, 1 of zinc and 0,3 of antimony was melted with a mixture of 40 per cent of antimony trisulphide, 20 of ferric chloride, 10 of zinc chloride and 30 of magnesium chloride. British Specification 342,586 and U.S.A. Specification 1,698,647 are referred to.
