As a kind of rare metals,rubidium is often used to prepare special glass,photomultiplier tubes,thermoelectric converter,organic catalysts and antidepressants.Rubidium forms no minerals of its own,hence,it often coexists

There are some isomeric compounds of 2:17 series of tungstophosphates, such as α and β isomers. The β isomer is not stable and is difficult to prepare. So it is rarely reported.
