摘 要:利用固体电解质作隔膜的有氧离子迁移的浓差电池Ⅱ和无氧离子迁移的复合浓差电池Ⅰ的电动势的测定结果推测了冰晶石-氧化铝熔体中氧离子迁移数。推测结果表明在冰晶石-氧化铝熔体中氧离子迁移数很小,约为0.006~0.012。
Abstract: The transference number of oxygen ion in cryolite-alumina melts was mea-sured by using two different concentration galvanic cells. It was found from the measurement that the transference number of oxygenion was very small and within 0.006~0. 012.
