铑铑rhodium一种化学元素。化学符号Rh,原子序数45,原子量102.9055,属周期系Ⅷ族,为铂系元素的成员。1803年英国W.H.渥拉斯顿从粗铂中分离出一种新元素,因它的许多化合物都呈鲜艳的玫瑰红色,故命名为rhodium,该字来源于希腊文rhodon,含义是“玫瑰”。铑在地壳中的含量为1×10-7%,常与其他铂系元素一起分散于冲积矿床和砂积矿床的多种矿物(如原铂矿、镍黄铁矿、硫化镍铜矿、磁铁矿等)中。独立矿物有硫砷钌铑矿,还以游离状态存在于自然合金(如锇铱合金)中。铑是银白色金属,熔点1966±3℃,沸点3727±100℃,相对密度12.4。质极硬,耐磨,有延展性,在热的状态下十分柔韧,可加工成细丝或薄片,铑还有良好的导电和导热性能。铑的化学性质不活泼,在空气中加热时,表面形成二氧化铑薄膜,加热至300℃与氯、溴发生反应。铑能耐酸和王水的侵蚀,但在200~600℃时与热的浓硫酸和氢溴酸发生反应。铑的氧化态为-1、+1、+2、+3、+4。以+3和+4价化合物稳定。铑容易形成配位化合物,如Cs[Rh(SO4)2]。用王水溶解经处理后的铂精矿或电解有色金属时产生的阳极泥,经一系列化学处理后,可得六氯合铑()酸铵,经灼烧后在氢气流中加热至1000℃,便被还原为海绵状金属铑。纯铑用于制电触头、低接触电阻的电接触器、高强度弹簧、高温电热丝、坩埚、电极等。铂铑合金用作电热丝、高温发热材料、热电偶以及氨氧化制硝酸、氢氰酸合成中的催化剂。铑铱合金用于制高级镜面和反光镜。
