1 生产现状高纯铝的应用包括铝制电解电容器与磁盘基片。霍尔-埃鲁法生产的铝的纯度为99.5～99.9％,必须经过进一步的精炼,才能获得高纯铝。日本采用的主要铝精炼法是三层液电解
1 production status of high purity aluminum applications include aluminum electrolytic capacitors and disk substrates. The purity of the aluminum produced by Hall-Elufa is 99.5-99.9%, which must be further refined to obtain high purity aluminum. The main aluminum refining method used in Japan is three-layer liquid electrolysis
