镍 nickel 一种化学元素。化学符号Ni,原子序数28,原子量58.69,属周期系Ⅷ族。古代埃及、中国和巴比伦人都曾用含镍量很高的陨铁制作器物,中国古代云南生产的白铜中含镍量就很高。1751年瑞典A.F.克龙斯泰德用木炭还原红镍矿制得金属镍,其英文名称来源于德文Kupfernickel,含义是假铜。镍在地壳中的含量为0.018%,主要矿物有镍黄铁矿〔(Ni,Fe)9S8〕、硅镁镍矿〔(Ni,Mg)SiO3·nH2O〕、针镍矿或黄镍矿(NiS)、红镍矿(NiAs)等。海底的锰结核中镍的储量很大,是镍的重要远景资源。 镍是银白色金属,熔点1455℃,沸点2730℃,密度8.90克/厘米3。有铁磁性和延展性,能导电和导热。常温下,镍在潮湿空气中表面形成致密的氧化膜,不但能阻止继续被氧化,而且能耐碱、盐溶液的腐蚀。块状镍不会燃烧,细镍丝可燃,特制的细小多孔镍粒在空气中会自燃。加热时,镍与氧、硫、氯、溴发生剧烈反应。细粉末状的金属镍在加热时可吸收相当量的氢气。镍能缓慢地溶于稀盐酸、稀硫酸、稀硝酸,但在发烟硝酸中表面钝化。镍的氧化态为-1、+1、+2、+3、+4 ,简单化合物中以+2价最稳定,+3价镍盐为氧化剂。镍的氧化物有NiO和Ni2O3。氢氧化镍〔Ni(OH)2〕为强碱,微溶于水,易溶于酸。硫酸镍(NiSO4)能与碱金属硫酸盐形成矾Ni(SO4)2·6H2O(MI为碱金属离子)。+2价镍离子能形成配位化合物。在加压下,镍与一氧化碳能形成四羰基镍〔Ni(CO)4〕,加热后它又会分解成金属镍和一氧化碳。 镍的制法有:①电解法。将富集的硫化物矿焙烧成氧化物,用炭还原成粗镍,再经电解得纯金属镍。②羰基化法。将镍的硫化物矿与一氧化碳作用生成四羰基镍,加热后分解,又得纯度很高的金属镍。③氢气还原法。用氢气还原氧化镍,可得金属镍。镍大部分用于制造不锈钢和抗腐蚀合金。镍还大量用于镀镍。镍铜合金用于电阻合金、热交换器和冷凝器管道。镍铬铁合金用于制造蒸气叶轮机和电热丝。在化学工业中镍用作加氢反应的催化剂。 |
