| Abstract: | The bubble's largest pressure method was employed to measure the densities and the surface tensions ofthe NaCl-KCl(equimolar)-ScCl3 system in which the contents of ScCl3 were 10%, 20%, 30% and 40%, respectively.The results show that while temperature increases, the densities and the sufface tensions of the melts will decrease at thesame content of ScCl3; while the content of ScCl3 in the melts increases, the densities of the melts will increase and thesufface tentions of the melts will decrease at the same temperature. The least-square method was used to treat the data,and the regression functions of the densities and the surface tensions with temperature were given. It is known from theresults that the physicochemical properties of the NaCl-KCl (equimolar)-ScCl3 system can meet the requirements ofpreparation of Al-Sc alloys through the molten salt electrolysis. |
