| titleOfInvention | The production method of hydrated lanthanum carbonate |
| abstract | An aqueous solution is obtained by reacting lanthanum oxide with an acid capable of forming a soluble salt of lanthanum, such as hydrochloric acid, adding a carbonate such as sodium carbonate to the obtained aqueous solution to make the pH of the aqueous solution 2.9 to 4.5, removing the generated solid content, and adding a solution to the obtained liquid. By adding carbonate to the components so that the pH becomes 5.5 to 7, hydrated lanthanum carbonate with low impurity element content and high purity can be produced. |
