    • A negative ion generating medium for generating negative ions from the surface of a mother material made of aluminum or aluminum alloy. The negative ion generating medium has the mother material of aluminum or aluminum alloy covered at the surface with an anodized layer on which a rare metal separated from a rare metal solution such as zirconium salt is deposited. As the rare metal is deposited in the pores provided in the anodized layer, its negative ion generating area can be increased thus releasing a large number of negative ions. The negative ion generating medium is manufactured by electrolytically processing the mother material in an electrolyte solution of sulfuric acid doped with a rare metal salt such as lithium salt to develop the anodized layer on the surface of the mother material and deposit the rare metal on the anodized layer.
    • 一种用于从由铝或铝合金制成的母材表面产生负离子的负离子产生介质。 负离子产生介质具有在表面覆盖有铝或铝合金的母材,其阳极氧化层沉积有稀有金属从诸如锆盐的稀有金属溶液中分离出来。 由于稀土金属沉积在阳极氧化层中提供的孔中,所以其负离子产生区域可以增加,从而释放出大量的负离子。 负离子产生介质通过在掺杂有稀有金属盐如锂盐的硫酸的电解质溶液中电解处理母体材料来制造,以在母材表面上形成阳极氧化层,并将稀有金属沉积在阳极化处理 层。
