中文摘要：
采用熔盐电脱氧法，在CaCl2熔盐中，以烧结的方式掺杂不同摩尔分数CaCO3粉末的ZrO2为阴极，石墨棒为阳极，温度为900℃，电压为3．1V,制备出锆。研究掺杂物及其浓度对阴极的形貌、电解反应的影响。结果表明：掺杂物CaCO3提高了ZrO2电解脱氧的速度；掺杂还增加电脱氧的有效反应面积，使电流效率提高，有效地缩短电脱氧所需的时间。
英文摘要：
Metal zirconium was prepared by electro-deoxidization method by using CaCl2 molten as electrolyte, sintered ZrO2 and ZrO2 doped different mole CaCO3 pallets as cathode, graphite rod as anode. The pallets were electrolyzed at 900℃ and 3.1 V for 8 h. It is found that the rate of electro-deoxidization reaction for ZrO2 and the current efficiency were increased, and the reaction time of Electro-deoxidization was shortened by adding CaCO3.
