| Abstract: |
| XRD was used to investigate phase compositions of solidified molecular electrolyte based on Na3AlF6-AlF3-KF-CaF2-Al2O3 system. Influence of different mass fraction of KF and CaF2 on phase formation in electrolyte was obtained. Change of phase in aluminum electrolyte system affects result of XRD method in analyzing molecular ratio of aluminum electrolyte. XRD method is improved to analyze molecular ratio of electrolyte sample according to phase formation law. Molecular ratio of electrolyte sample before and after improvement was compared. The results show that improved XRD method is suitable for analyzing molecular ratio of aluminum electrolyte containing high mass fraction of potassium and calcium fluoride salt. |
