    摘要:

    利用電脫氧法(FFC)從NiO-CeO2、NiO-SnO2氧化物制備CeNi5、Ni3Sn2。以不同溫度燒結(jié)的混合氧化物試樣作陰極，石墨碳棒作陽極，在850 ℃的CaCl2熔鹽中，3.1 V電壓下完成反應(yīng)。采用SEM和XRD分析電解前后試樣形貌及相組成。結(jié)果表明：燒結(jié)溫度越高，試樣的孔隙率越低，電解電流越小；不同溫度燒結(jié)試樣可電解出純CeNi5相，低溫?zé)Y(jié)試樣可電解出純Ni3Sn2相，產(chǎn)物為疏松的海綿狀。本實(shí)驗(yàn)為電池材料提供了一種新的制備方法

    Abstract:

    CeNi5 and Ni3Sn2 were prepared from NiO-CeO2 and NiO-SnO2 oxides by electro-deoxidization (FFC). The samples of mixed oxides sintered at different temperatures were used as cathode, and the graphite rod was used as anode. Then the reaction was completed under 3.1 V in the CaCl2 solution at 850 oC. The morphology and phase composition of the samples before and after deoxidization were analyzed by SEM and XRD. Results show that the sample has lower porosity and smaller electro-deoxidization current under the condition of higher sintering temperature. The product from samples sintered at different temperatures was pure CeNi5; the product from samples sintered at lower temperature was pure Ni3Sn2 with loose sponginess. The research provides a new method for cell materials preparation
