Facts Interesting
- Lanthanum logam punika Highly malleable, ductile lan sectile.
- Yen kapapar logam Lanthanum online oxidizes kanthi cepet.
- Unsur cilik sing alami kalebu Kadmium.
- Kadmium dibebasake menyang atmosfer kanggo ngontrol letusan gunung geni lan kebakaran alas.
- Kang digunakake kanggo electroplating saka Steel kanggo resistance karat.
- Bisa nyerep neutron lan digunakake ing reaktor nuklir kanggo ngontrol fisi atom.

Ulah lan Wuku
- Ora ana panggunaan komersial, nanging paduane akeh dikarepake. Lanthanum lan Nikel alloy digunakake kanggo panyimpenan gas hidrogen.
- Panggunaan paling misuwur kanggo campuran mischmetal saka Lanthanum yaiku; minangka 'flints' kanggo korek rokok.
- Wis Efesus banget winates minangka logam beracun lan bisa nimbulaké cacat lair, kanker, etc.
- Meh 80% saka logam kadmium digunakake ing Nikel Baterei kadmium lan saiki lagi njupuk diganti karo isotop nikel.
