Because cesium is not mined domestically, the United States is completely dependent on imports. Historically, the most important use for cesium has been in research and development, primarily in chemical and electrical applications. Rubidium was discovered in 1861 but had extremely limited industrial use until the 1920s.

Alkali Metals Group 1 (IA) This family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium (Li, Na, K, Rb, Cs, and Fr, respectively). Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive.

Rubidium Uses. Rubidium and its salts or components have few commercial uses. Because of rubidium can be easily ionized, it has been considered for use in "ion engines" for space vehicles, but was found to be less effective than caesium. It has also been proposed for use as a working fluid for vapour turbines and in thermoelectric generators.
