of molybdenum oxides by aluminum and silicon were calculated, and the results show that reduction reaction is feasible at a certain temperature region. Compared to the presence of CaO or CaCO3, reduction products of molybdenum trioxide with aluminum and silicon at various temperatures were detected by X-ray diffraction(XRD). Results show that molybdenum trioxide is reduced by aluminum or silicon step......
> Abstract: A hypereutectic aluminum-silicon alloy with content of 17%Si, designed as A390, was modified. The change of microstructure was identified by optical microscopy. The results show that phosphorus can change the morphology and size of the primary silicon and control the length of needle-like eutectic silicon or dendrite. After modified by phosphorus, the primary......
