- 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.
- Panggunaan utama Lithium wis Manufaktur strum maneh batre kanggo peralatan elektronik lan Gadgets.
- iku uga digunakake ing Manufaktur batre non-strum.
