化学的特性White powder.Extremely hygroscopic; soluble in water. Dissociates above 900C. The thermal decomposition of rubidium carbonate to produce rubidium oxide and carbon dioxide. This reaction takes place at a temperature of over 900°C in vacuo. The decomposition of Rb2CO3·3H2O2 and Cs2CO3·3H2O2 under isothermal conditions was studied (55–85°) and it was shown that the decomposition of these compounds is self-accelerated. The final products are M2CO3, H2O, and O2. Rb2CO3·3H2O2 has a much higher thermal stability than Cs2CO3·3H2O2.

説明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].
