Research Trends on the Transport Characteristics and Microstructure of High Temperature Molten Salt in Aluminum Electrolyte

Abstract

电解质作为铝电解槽中的“血液”，其组分与特性变化直接影响着电解工艺的控制以及槽操作管理。因而，研究者针对铝电解质高温熔盐离子结构以及物理化学等宏观性质等方面进行了大量测试以及理论方法研究。本论文围绕铝电解质熔盐的输运特性，总结归纳当前的主要测试研究方法；同时，简要分析了熔体离子结构的主要研究方法，重点介绍了熔体离子结构与输运特性的理论计算方法，并提出相应建议。 As the “blood” in aluminum electrolytic cell, the composition and characteristic of electrolytes directly affect the control of electrolysis process and the operation and management of the tank. Therefore, researchers have carried out a lot of tests and theoretical studies on the ionic structure and macroscopic properties of high temperature molten salt. In this paper, the main testing and research methods are summarized based on the transport characteristics of molten salt. At the same time, the main research methods of melt ion structure are briefly analyzed, the theoretical calculation methods of ion structure and transport characteristics are mainly introduced, and corresponding suggestions are put forward.
