History and Uses:
Rubidium was detect by the German chemists Robert Bunsen and Gustav Kirchoff in 1861 while analyzing samples of the mineral lepidolite (KLi2Al(Al, Si)3O10(F, OH)2) with a device called a spectroscope. The sample produced a put in of deep red spectral lines they had never seen before. Bunsen was ultimately able to isolate samples of rubidium metal. Today, most rubidium is obtained as a byproduct of refining lithium.
Rubidium is used in vacuum tubes as a getter, a material that combines with and removes tip gases from vacuum tubes.



It is also used in the manufacture of photocells and in special glasses. Since it is easily ionized, it might be used as a propellant in ion engines on spacecraft. Recent discoveries of commodious deposits of rubidium suggest that its usefulness will increase as its properties become better understood.
