'''Lantan''' je [[1839.]] godine otkrio [[Švedska|Šveđanin]] [[Carl Gustaf Mosander]]. Ime je dobio od [[Starogrčki jezik|grčke]] riječi ''lanthano'', što znači biti skriven. To je srebrno bijeli, kovki metal. Dovoljno je mekan da se može rezati nožem. Brzo oksidira na zraku, dok s hladnom vodom reagira sporo uz razvijanje [[vodik]]a.<br />
<br />
Lantan se koristi kao metal za [[slitina|legiranje]] s [[kobalt]]om i [[nikl]]om za izradu permanentnih magneta, u grafitnim elektrodama, [[krekiranje|krekiranju]]. [[Lantanov oksid]] se koristi pri izradi [[termistor]]a, kondenzatorskih [[dielektrik]]a, optičkih stakala i u novije vrijeme za krekiranje.<br />
