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%
