锌汞齐(即锌汞合金)是有色冶炼行业生产的有色金属功能材料之一,是制造碱性锌锰电池、银锌电池等一类碱性电池的材料,用以制作电池的阴极。制造锌汞齐的传统方法是向锌粉加金属汞,经过一定时间的混合而成。这种方法的缺点是汞的分布不均匀,用以制造的电池,使用寿命短。采用熔炼方法熔炼的锌汞齐,汞的分布均一,能用以优质造制电池。我国用以制造优质碱性电池的进口锌汞齐,皆是熔炼法生产的锌汞齐。
Zinc amalgam (zinc-amalgam) is one of the non-ferrous metal functional materials produced in the non-ferrous smelting industry. It is a kind of alkaline battery material for manufacturing alkaline zinc-manganese batteries, silver-zinc batteries and the like, and is used for making the cathode of a battery. The traditional method of making zinc amalgam is to add metallic mercury to zinc dust and mix it over a period of time. The disadvantage of this method is the uneven distribution of mercury, used to manufacture batteries, short service life. Smelting using smelting zinc amalgam, mercury distribution is uniform, can be used to create quality batteries. China’s imports of zinc amalgam for the manufacture of high-quality alkaline batteries, are all produced by melting zinc amalgam.
