Physical and Chemical Properties | Colorless orthogonal or hexagonal crystals. The specific gravity was 3.613. Melting point 1060 °c. Boiling point 1700 °c. Soluble in water, insoluble in acetone. Easily with aluminum, chromium, gallium, indium and ferric iron and other metal sulfate formation of alum. By the action of aluminum rubidium alum and barium hydroxide solution, the aluminum hydroxide and barium sulfate precipitates were removed by filtration, and then the solution was concentrated by evaporation. |
Use | Raw materials for the preparation of metal rubidium and various rubidium salts, catalysts, miniature high-energy batteries and crystal scintillation counters. |
