- nggunakake paling umum saka logam Sesium yaiku adi ngebur. Sampeyan uga dipigunakaké ing Manufaktur kaca optik.
- Ing tabung vakum lan peralatan monitor radiation logam iki digunakake minangka katalis tukang promosi.
- 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.
