| description | The application of Ce oxides in oxide metallurgy has received extensive attention, but until now, the direct adding of CeO<sub>2</sub> into molten steel to generate Ce oxides has not occurred. In this paper, a mixture of CeO<sub>2</sub> and Si nanoparticles were added into molten steel. The resultant formation of micrometer scale Ce-bearing oxides confirmed its adding validity. This behavior may be interpreted as the reactivity between CeO<sub>2</sub> and [Al], and the improved wettability between CeO<sub>2</sub> and molten steel with the assistance of Si powder. Thus, when the quantity of CeO<sub>2</sub> is kept constant, its added yield should increase when increasing the added quantity of Si. This was verified by the larger percentage of Ce-bearing oxides of the total oxides and the greater average content of Ce in Ce-bearing oxides after normalization. Moreover, compared with the blank sample, statistical results indicated that the oxides in CeO<sub>2</sub>-modified samples were refined, and their dispersion homogeneity was enhanced. This comparison indicates the effectiveness of the external adding method in oxide metallurgy. |
