- Kang digunakake kanggo kalebu flints kanggo korek rokok.
- Sawijining senyawa Cerium (Gerah) oksida digunakake minangka katalis; sijine nang tembok saka open minangka ngalangi saka buildup saka ampas masak.
- 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.
