Most widespread minerals containing Rubidium; This list of minerals containing Rubidium is built from the locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rockformingminerals so it does not give an undistorted distribution of Rubidium mineral ...

Rubidium is the chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silverywhite metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the ...

Rubidium has been used for polarizing 3He (that is, producing volumes of magnetized 3He gas, with the nuclear spins aligned toward a particular direction in space, rather than randomly). Rubidium vapor is optically pumped by a laser and the polarized Rb polarizes 3He by the hyperfine interaction.
