Resumen o descripción
In this work cenospheres, zeolite, silica or mixtures of them were injected
into amolten aluminumalloy using argon as a carrier gas in order tomeasure
their efficiency as Mg removers. The Mg content of the molten alloy was
measured during the injection period and the produced dross was weighted
for each experiment. The physicochemical characterization and the use of
the thermodynamic software FactSage version 6.2, allowed the
determination of the reaction mechanism between the powders and the
molten aluminum. Cenospheres demonstrated their capacity as Mg
removers with an efficiency similar to silica but lower than that
corresponding to zeolite and zeolite:silicamixtures. The use of a zeolite:silica
mixture (65:35wt%) produced the best results, removing the magnesiumof
the alloy from an initial content of 1wt% to a final content of 0.0072wt%
