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.
- 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.
