Rubidium Uses

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 In the actual only those who are trained to handle pure rubidium can deal with the chemical element Get price



Rubidium is a soft and silvery-white element which belongs to the alkali metal group Rubidium was discovered by German chemists Robert Bunsen and Gustav Kirchhoff in 1861 Rubidium is the 23 rd most abundant element in the earth's crust and the main sources of rubidium are leucite pollucite carnalite and zinnwaldtie Get price

Stability and Noise Performance of Various Rubidium

Of course no conventional rubidium-vapor clock can serve as a drift-free primary standard so cesium-beam technology was in no danger of obsolescence when HP announced the 5065A But now over forty years later everyone has access to a perfectly usable (if noisy) primary standard in the form of cheap GPS-disciplined oscillators Get price



The Model LPRO-101 makes use of the atomic resonance property of Rubidium (87 Rb) to control the frequency of an unheated quartz crystal oscillator via a frequency-locked loop (FLL) All commercial rubidium frequency standards operate by disciplining a crystal oscillator to the hyperfine transition at 6 834 682 612 GHz in rubidium Get price
