Process for optimising the reaction of hexachloroethane for the degassing of molten aluminium and of aluminium alloys and also the distribution of crystallisation nuclei in them

摘要

For the purpose of the chlorinating degassing of molten aluminium and of aluminium alloys, the invention provides a combination of hexachloroethane and a reactive metal, in particular aluminium. This affects the hexachloroethane decomposition in such a way that the formation of highly chlorinated aromatic hydrocarbons which normally occurs is largely suppressed.
