METHOD OF PREPARING ALUMINIUM-SILICIUM ALLOYS Russian patent published in 1996 - IPC

Abstract RU 2063460 C1

FIELD: alloy production. SUBSTANCE: quartz sand is added to the aluminium melt in amount 20-25% calculated on the melt weight. The mixture obtained is treated at 800-850 C with products of the reaction of steam with a carbonaceous stuff for 15-20 min. After further 30-40 min the melt is poured out. The yield of silumine is 11-16% higher. EFFECT: increased silicium content. 1 tbl
