在原料中添加石墨粉制备了ZrO2-Ni2O3烧结片,并将其作为阴极片进行直接电脱氧制备ZrNi合金。研究了添加石墨粉对烧结片形貌和组成、阴极电脱氧反应的影响。结果表明,与未添加石墨粉的情况相比,添加石墨粉制备的烧结片颗粒尺寸更均匀,孔隙度更高;阴极电解电流更高,电脱氧反应更快;电解产物中ZrNi合金相的含量也更高,其质量分数达82%(氧化-称重法测定)甚至94.6%(微区EDS分析)。 ZrO2-Ni2O3 sintered sheet was prepared by adding graphite powder into the raw material, which was then directly electro-deoxidized to prepare ZrNi alloy. The effects of adding graphite powder on the morphology and composition of the sintered sheet and the cathodic deoxidation reaction were studied. The results show that the sintered particles prepared by adding graphite powder have more uniform size and higher porosity than those without graphite powder, higher cathodic electrolysis current and faster electro-deoxygenation reaction. The content of ZrNi alloy phase in the electrolysis product Also higher, with a mass fraction of 82% (oxidation-gravimetric method) or even 94.6% (Micro EDS analysis).
