Effects of different carbon distribution on the extraction of silicon aluminium alloy by carbon reduction fly ash were studied. X-ray diffraction instrument was used to characterize phases of the products. The results showed that when the carbon content was 0.8 to 1.0 times that of carbon, alumina and silicon carbide were included in the reduction products. When the carbon content was 1.1 times that of carbon, the reduction products were Al, Al 4.5 FeSi, Si, SiC and FeSi 2 . When the carbon content was 1.2 times that of carbon, the reduction products were SiC, Si, Al and Al 4.5 FeSi. With the increase of the amount of carbon, the effect of preparing silicon aluminium by carbon reduction fly ash was better. In this experiment, when the carbon content was 1.2 times that of carbon, the carbon reduction fly ash had the best preparation effect on silicon aluminum alloy.
