【摘要】 采用交流阻抗谱技术测定熔盐电阻,并通过CVCC法研究了在1 020～1 120℃的温度范围内NdF3-LiF-Nd2O3熔盐体系的电导率,确定了温度、Nd2O3含量与熔盐电导率之间的关系,分析了温度和Nd2O3含量之间的相互作用以及对熔盐电导率的影响。研究结果表明,温度增加、Nd2O3含量减少,则电导率增大;在温度为1 080℃,Nd2O3含量为1.5%、2%、3.5%时,熔盐电导率变化幅度小,体系较为稳定。更多还原

【Abstract】 The electrical conductivity of Nd2O3-NdF3-LiF molten salt were measured by Continuously Varying Cell Constant(CVCC) technique between 1 020 and 1 120 ℃ upon testing molten salt resistance with AC impedance spectrum method.The linear relationship between temperature,Nd2O3 and electrical conductivity were determined.The interaction between temperature and Nd2O3 contents and its impact on the electrical conductivity of the molten salt is analyzed.The results show that the electrical conductivity of the molten salt increases with rising temperature and reduced Nd2O3 contents.The electrical conductivity changes slightly at 1 080(the Nd2O3 contents are1.5 %,2 % and 3.5 % respectively).更多还原
