Ulah lan Wuku
- 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.
- metal Curium digunakake kanggo nyedhiyani daya kanggo peralatan listrik kanggo papan misi.
