Facts Interesting
- Cerium minangka logam bumi langka nanging isih ora langka.
- Iku senyawa non-beracun Cerium sulfida nduweni werna abang sugih lan digunakake minangka pigmen.
- Logam Cerium uga digunakake ing TV layar datar, bolam lampu, lampu sorot, lsp.
- Sumber utama Kobalt minangka produk sampingan saka pertambangan logam tembaga lan nikel.
- Logam kobalt bisa dipikolehi saka unsur liyane kayata Oksigen, Sulfur lan Arsenik.
- Uga digunakake ing proses electroplating amarga nuduhake sifat anti cession.
