| titleOfInvention | Method for preparing high-purity rubidium by one-step thermal reduction of metal calcium |
| abstract | The invention discloses a method for preparing high-purity rubidium by one-step thermal reduction of metal calcium, which comprises the steps of taking metal calcium particles with the purity of more than 95% and rubidium chloride powder with the purity of 98.0-99.9% as raw materials, mixing the metal calcium particles with the rubidium chloride powder, taking stainless steel as a container, placing the container in a horizontal vacuum electric furnace to be heated to 842-1390 ℃ under inert atmosphere, carrying out thermal reduction displacement reaction, guiding metal rubidium steam to a condensation part under vacuum suction force through a heated straight-through pipeline, condensing the metal rubidium steam into liquid drops, and enabling the purity of the obtained liquid metal rubidium to reach 99.50-99.99%. The invention provides a process for preparing high-purity rubidium by adopting a reducing metal one-step heating method, complex processes such as multiple heating reduction, electrolysis, distillation and the like are not needed, and the process has the advantages of simple and feasible purification process, low cost, environmental friendliness, no pollution, safety and reliability, and is suitable for continuous industrialization. Compared with the prior art, the method has better practicability and industrialization advantages. |
