Rubidium carbonate is a white powder or colorless crystal with a monoclinic crystal structure. Its chemical formula is Rb2CO3. Rubidium is often sold as rubidium carbonate The chemical properties of rubidium carbonate are stable. Rubidium carbonate is very hygroscopic, soluble in water, and insoluble in alcohol. It can be converted to other rubidium compounds by heating or by reacting with acids. Rubidium carbonate is used in the preparation of rubidium metal, other rubidium salts,and rubidium single crystals. It is also used as a specific glass additives, catalysts, analytical reagents and others. For example, rubidium carbonate can be incorporated into the metal oxide electron transport layers, which can improve the lifetime of quantum-dot light emitting diodes[1]. It can also exist as an alkaline in the high-temperature nucleophile synthesis of a semi-crystalline, aromatic poly(ether ketone)[2].

| [Uses]
Rubidium carbonate is used in special glass and in fiber optics. It enhances stability and durability of glass, reducing its conductivity. It also is used in the preparation of Rb metal and other rubidium salts.
| [Preparation]
Rubidium carbonate is an intermediate in recovery of rubidium from lepidolite. The mineral, on prolonged heating with concentrated sulfuric acid, converts to alums.
The mixed alum solution, on treatment with ammonia or potassium carbonate, forms carbonates of potassium, rubidium and cesium. Rubidium carbonate is separated from other alkali metal carbonates by fractional crystallization (see Rubidium)
The carbonate salt also may be obtained by passing carbon dioxide through a solution of rubidium hydroxide in a fluorocarbon or nickel container. The solution is evaporated to yield the product carbonate.
Also, the salt may be prepared by adding ammonium carbonate to a solution of rubidium hydroxide. The solution is evaporated to dryness to expel ammonia.
