| 摘 要： | 采用平行四电极法研究了温度及组元含量对KCl-NaCl-NaF—SiO2熔盐体系电导率的影响。结果表明：该体系的电导率与温度有良好的线性关系；用KCl逐步代替NaF时，体系的电导率先逐渐减小达到最低值，之后随KCl含量增加又逐渐增大；NaCl逐步代替NaF时，体系的电导率先减小到最低值，之后随NaCl含量增加又逐渐增大；在n（NaCl）：n（KCl）=1时，随NaF含量增加，体系电导率先逐步减小到最低值，之后随NaF含量增加又逐渐增大。

| Abstract: | Four parallel electrode method has been applied to investigate the conductivity of NaCl-KCl-NaF-SiO2molten salt system.The results show that there has favourable linearity relation between system conductivity and temperature.Stage by stage,substituting KCl for NaF decreases conductivity of the system to minimum,then the conductivity increases along with KCl.Replacing NaCl for NaF falls the conductivity of the system to minimum,then the conductivity increases along with NaCl.At the ratio of n(NaCl) to n(KCl)... |
