ABSTRACT:
Briquettes or tablets to be added to an aluminium melt, are made up by the combination of an agglutinated powder which include, at least, an aluminium powder, a powder of one or more metals or alloys including those to be added, and a wax-type organic compound, all in adequate proportions. This combination allows the increase of the dissolution velocity of the added metals, the recoveries of the added metal, a better stirring of the melting aluminium, and the reduction of impurities and of accumulated metal in the bottom of the furnace.
