| titleOfInvention | Method for producing high-purity strontium carbonate |
| abstract | (57) Abstract: Alkali metals such as Na, heavy metals such as Fe and Ni, radioactive elements such as U and Th, and high purity strontium carbonate with a low impurity content such as Ca, which is a homologous element to strontium. Develop manufacturing methods. A method for producing high-purity strontium carbonate, which comprises adding an acid to a strontium-containing aqueous solution to precipitate a strontium salt, solid-liquid separating the precipitated strontium salt, and then carbonating the strontium salt. As the acid added to the strontium-containing aqueous solution, It is preferable that the acid concentration of nitric acid, hydrochloric acid or a mixed acid thereof, or the strontium-containing aqueous solution after the acid addition is 5 to 12 N, and the acid after the solid-liquid separation is distilled and recovered and reused. |
