Rubidium carbonate is an inorganic compound with the chemical formula Rb₂C O₃. It is a white, hygroscopic solid that readily dissolves in water.

Preparation

Rubidium carbonate can be prepared by reacting ammonium carbonate and rubidium hydroxide.^[4]

It is used in glassmaking to enhance stability and durability whilst reducing conductivity.^[5]

It is also used as a part of a catalyst to prepare short-chain alcohols from feed gas.^{[citation needed]}
