Carbonic acid dirubidium salt - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Chemical reagents and chemical, glass industry raw materials | Appearance of Rubidium carbonate is colorless crystals, often powder, there is a strong hygroscopic deliquescence. The melting point was 837 °c, and the decomposition began when heated to 750 °c. Soluble in water, insoluble in ethanol. The aqueous solution is strongly alkaline. It is often present in the form of a hydrate. Process: From the reaction of rubidium hydroxide and carbon dioxide or from rubidium oxalate or Rubidium hydrogen tartrate heat decomposition and made. Purposes: for chemical reagents and chemical industry and glass industry raw materials. Rubidium carbonate can be reduced by magnesium to form rubidium metal. Rubidium carbonate and acid interaction, both carbon dioxide release, while generating the corresponding compounds of rubidium. The reaction formula of the interaction between Rubidium carbonate and magnesium carbonate in carbon dioxide saturated aqueous solution is as follows: Total reaction formula: Rb2CO3 CO2 H2O 2MgCO3=2RbHMg(CO3)2 Rubidium carbonate solution and iodine pentoxide, and release carbon dioxide. When the Rubidium carbonate solution reacts with iodine pentoxide, the precipitate of Rubidium iodate is formed and carbon dioxide is released. After heating the Rubidium carbonate solution with molybdenum trioxide, it is saturated with sulfur dioxide at room temperature, and white crystals are formed. (2016-01-13) |
| Use | as an analytical reagent, also used for the synthesis of other rubidium salts Rubidium carbonate is generally used for the preparation of other basic raw materials of rubidium salts, but also used in the preparation of raw materials containing rubidium single crystal, special glass, ceramic industry and other fields. basic raw materials of other rubidium salts, raw materials containing rubidium single crystal, used in special glass, ceramic industry, chemical industry as catalyst, etc. raw materials for preparing metal rubidium and various rubidium salts, the production of special glass, miniature high-energy batteries and crystal scintillation counters. |
