摘 要：This work presented the feasibility of cerium recovery by Al-Mg alloy through the metallothermic reduction of CeO2 to obtain a master alloy Al-4%Ce.The master alloy obtained in this investigation was for the grain refinement and modification of Al-Si alloys.The re-agent was incorporated into a molten alloy using the submerged powder injection technique,and metallic samples were obtained during injec-tion.Chemical and microstructural analyses （by inductively coupled plasma （ICP） and scanning electron microscopy （SEM）,respectively） confirmed the possibility of Ce uptake in the bath （0 to 4 wt.%）,as CeO2 was reduced through metallothermic reactions in the molten alloys.Based on the characterization of reaction products,the sequence of the reaction was proposed.
