The international primary standard for the kilogram is made of 90% platinum, 10% iridium. Platinum has valence 2 or 4 in its compounds, which include many coordination complexes. It and some compounds are useful catalysts, particularly for hydrogenation and in catalytic converters for reducing automobile emissions.

重量和长度的国际标准原型用90%的铂,10%的铱制成。76.7%铂与23.3%钴的合金是已知最强的永久磁体。铂在它的原子价里有2价或4价。这些化合物中有许多是配位错合物。铂与它的某些化合物都是有用的催化剂,尤其用于氢化作用中,以及用作催化转化剂。
