Rubidium compounds are sometimes used in fireworks to give them a purple color. Rubidium has also been considered for use in a thermoelectric generator using the magnetohydrodynamic principle, where hot rubidium ions are passed through a magnetic field.


Rubidium is not particularly harmful to humans, and once in the body its ions are rapidly excreted in sweat and urine. Rubidium chloride has been used to study the transport of potassium ions in humans, since rubidium ions are not naturally found in the body and when present they are treated as if they were potassium.


As rubidium is an element in the earth's crust, it is a constituent of soil in which plants grow. Rubidium is agile enough to seep into plants. This is how rubidium enters the food chain and becomes a constituent, with our daily intake of the component ranging from 1 to 5 mg. There are no specific rubidium uses in everyday life.


Rubidium is pronounced as roo-BID-ee-em. History and Uses: Rubidium was discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 while analyzing samples of the mineral lepidolite (KLi 2 Al(Al, Si) 3 O 10 (F, OH) 2) with a device called a spectroscope. The sample produced a set of deep red spectral lines they had never seen ...


Rubidium is a silvery-white and very soft metal — and one of the most highly reactive elements on the periodic table. Rubidium has a density about one and a half times that of water and is solid ...


The following uses for rubidium are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses.. rubidium is easily ionized, and so has possible use in "ion engines" for space vehicles (but caesium is somewhat more efficient)


What is Rubidium? Rubidium is a chemical element of group 1 (the first column on the periodic table) with the abbreviation Rb and atomic number 37. As a member of the alkali metals, rubidium has ...


Rubidium Uses. Industrially, it is commonly used in photocells, vapor reference cells (with quartz), lasers, to make special types of glass and as a getter to remove trace gases from vacuum tubes [1, 3]. Easy ionization has led to its application in ion engines, though it was found to be less effective than cesium [1].


Uses of Rubidium. Rubidium is used in photocells, as a getter (remover of trace gases) in vacuum tubes and as working fluid in vapor turbines. Rubidium-87 is slightly radioactive and has been used extensively in dating rocks. Rubidium compounds give a purple color in fireworks.


Common rubidium compounds include rubidium chloride, rubidium monoxide and rubidium copper sulphate. A combination of rubidium, silver and iodine is potentially useful in film batteries due to its electrical properties. Lenntech states that rubidium, part of the alkali metal group, is soft and appears as silvery-white and metallic.
