钴是银白色的、具有磁性的一种非常稀有的金属,其来源目前几乎全来自铜或银生产过程中的副产物。钴结晶有两种同位异构体,即α型(六边形晶体)和β型(矩形晶体)。工业上它被分为纤维型的和非纤维型的两类。 钴广泛地用于工业上和医学上。工业上它不仅用于制造合金、颜料、催化剂、催干剂、 Cobalt is a silvery white, magnetically very rare metal whose source is currently almost entirely from by-products of copper or silver production. There are two kinds of isomers of cobalt crystal, namely α type (hexagonal crystal) and β type (rectangular crystal). It is classified industrially into two types: fiber type and non-fiber type. Cobalt is widely used in industry and medicine. It is not only industrially used to make alloys, pigments, catalysts, driers,
