Abstract
Oxides and gases are removed from aluminium and aluminium alloys by means of a mixture of carbon tetrachloride and an alkali bifluoride, particularly ammonium bifluoride, with or without the addition of silicon chloride. Carbon tetrachloride may be wholly or partly replaced by antimony pentachloride or manganous chloride or both. If the aluminium alloys to be treated contain zinc, zinc chloride with or without silicon chloride may be used along with the above reagents. Liquid chlorides used as reagents may be absorbed in charcoal powder before use. The purification of an aluminium alloy containing 0,5 per cent of antimony, 1,4 per cent of manganese, and 2 per cent of magnesium is referred to.
