Resumen o descripción
In order to improve the Mg removal from an A-380 molten alloy, mixtures
of mineral silica and amorphous silica nanoparticles (SiO2(NP´s)) were
tested. Mineral silica was enriched with 2.5, 5 and 10wt% of amorphous
SiO2(NP´s). Before Mg removing, samples of mineral silica were impregnated
with SiO2(NP´s) bymixed for 30 min in ethanol and then dried at 110°C
for 24 h. The enriched mineral silica with nanoparticles was analyzed by
scanning electron microscopy and transmission electron microscopy. The
Mg removal was carried out injecting each mixture into the molten aluminum
alloy at 750°C using argon as a carrier gas. The Mg content of the
molten alloy was measured after different periods of injection time (each
10 min). It was found that the mineral silica with 10wt% of SiO2(NP´s) is the
most efficient mixture, removing Mg from an initial content of 1.6 to a
final content of 0.4wt%, in 70 min of injection. Moreover, thermodynamic
predictions were carried out in the FactSage software in order to
establish chemical equations occurring in the system.
