Ulah lan Wuku
- Kang digunakake kanggo riset waé. jumlah cilik saka logam digunakake ing batre atom.
- bosok radioaktif sawijining digunakake kanggo Phosphor kanggo menehi mati lampu. Lampu cemlorot diowahi dadi listrik.
- 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.
