镍广泛地分布于地球外壳,平均含量为80ppm,多数工业上的镍,来源于各种混合硫化镍矿,如镍黄铁矿、镍共生磁黄铁矿、镍共生黄铜矿等。镍主要用于冶金工业:50％以上是与铁制成铁镍合金生产不锈钢,25％制造镍铜和镍铬合金,25％左右直接以纯金属使用或作镍保护性外层。镍也用在搪瓷底层,以改善搪瓷附着基础:着色陶瓷和玻璃;爱迪生型蓄电池和制造特殊镍粉。此外,
Nickel is widely distributed in the earth’s crust, with an average content of 80 ppm. Most industrial nickel comes from various mixed nickel sulphide ores such as pentlandite, nickel symbiotic pyrrhotite and nickel symbiotic chalcopyrite. Nickel is mainly used in the metallurgical industry: over 50% is made of iron-nickel alloy with iron to produce stainless steel, 25% nickel-copper and nickel-chromium alloy, about 25% pure metal or nickel protective outer layer. Nickel is also used on the bottom of enamel to improve the foundation of enamel attachment: colored ceramics and glass; Edison-type batteries and special nickel powder. In addition,
