3.1 Ulah lan Wuku

Punika digugat ing Manufaktur Paint kimia lan Manufaktur kaca.
Senyawa saka logam beracun; nanging isih barium sulfat punika insoluble lan diwenehi kanggo patients gerah saka kelainan pencernaan.

metal Holmium duwe kemampuan kanggo nresep neutron, supaya logam iki digunakake ing reaktor nuklir kanggo njaga reaksi berantai saka unsur ing kontrol.
Wesi saka Holmium digunakake kanggo gawé Magnet.
