Ulah lan Wuku
- Panganggone Scandium mung diwatesi kanggo riset. Nanging, kapadhetan banget kurang lan titik leleh sing luwih dhuwur.
- Senyawa kaya skandium iodida digunakake ing lampu uap merkuri kanggo ngasilake cahya putih sing padhang banget.
- Magnet saka campuran kobalt Samarium luwih kuwat tinimbang wesi lan mula digunakake ing aplikasi gelombang mikro.
- Logam Samarium uga digunakake ing laser optik lan kaca tingal nyerep infra merah lan minangka penyerap neutron.
