旋转圆盘电极装置在冶金方面的应用-铝冶金中氧化铝溶出电解法研究

Alumina dissolution in cryolitic electrolytes has been a subject of intensive studies, and its relation to the alumina physical
properties had been attempted through various studies over past decades as reported in the open literature. The findings from
these reported lab studies have been proved to be difficult to relate alumina dissolution rate in industrial operating cells due to
lack of similarities between the two settings. Alcoa has been using a different experimental approach to measure alumina
dissolution rate to monitor ore quality changes for providing necessary information to our smelting operations. This paper
briefly describes the background for alumina dissolution studies, experimental setup and procedures for measuring dissolution
rate. Some comparison results of typical good and bad alumina ores in term of dissolution rate are presented. 旋转圆盘圆环电极（E7R9 RRDE 318m)/旋转环盘电极 旋转圆盘电极/MSR装置
