Abstract (en)

This is referred to the fabrication of some addition elements by means of briquettes or tablets made up by the combination of an agglutinated powder which comprises, 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 to increase 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.
