Rubidium carbonate, Rb₂C O₃, is a convenient compound of rubidium; it is stable, not particularly reactive, and readily soluble in water, and is the form in which rubidium is usually sold.

Preparation

This salt can be prepared by adding ammonium carbonate to rubidium hydroxide.^[3]

Uses

It is used in some kinds of glass-making to enhance stability and durability and reduce conductivity. It is also used as a part of a catalyst to prepare short-chain alcohols from feed gas.^[4]
