| 摘 要： | 采用电化学交流阻抗谱法研究了Na3AlF6(冰晶石)-Al2O3熔盐体系的总电导以及CaO加入对其电性能的影响. 根据测得的阻抗谱,提出了等效电路,用EvolCRT电化学软件对阻抗数据进行了拟合. 获得了Na3AlF6-Al2O3体系电导率随温度及Al2O3浓度变化的数学关系. CaO加入使得体系电导率增加.

| Abstract: | The total electric conductivity of Na3AlF6-Al2O3 slag and the effect of added CaO on the electric conductivity of the slag were investigated by the Ac impedance method of electrochemistry.Equivalent circuits were proposed according to the measured impedance spectra.EvolCRT electrochemical software was used to simulate the impedance data.The correlations of conductivity to slag composition and temperature were studied.The addition of CaO increases the electric conductivity of the system. |
