Ulah lan Wuku
- Lutetium logam digunakake njaba riset. Wis komersial kaya katalis Industrial kanggo gawe panyulingan lenga hidrokarbon.
- aplikasi utama Rubidium iku ing Manufaktur kaca.
- Rubidium bisa banget gampang njaluk ionized lan Empu iku digunakake kanggo mesin ion, nanging isih kurang efisien tinimbang sing saka Caesium.
