- 7. Uses of Rubidium Thereare few uses outside of research for rubidium There has been some research done in the development of thinner batteries Has been prospected for a working fluid for vapor turbines and in thermoelectric generators Used as a photocell component Can be found in some special optical glasses Its slight radioactivity has been used to find brain tumors, because it collects at the site of a tumor and
