Abstract

El hidrato de carbonato de lantano de alta pureza que tiene un contenido de impurezas de elementos pequeños se puede producir al añadir una sal de carbonato, por ejemplo, carbonato de sodio, a una solución acuosa preparada al hacer reaccionar óxido de lantano con un ácido capaz de producir una sal soluble de lantano, por ejemplo, ácido clorhídrico, para ajustar el valor de pH de la solución acuosa de 2.9 a 4.5 para producir una materia sólida, luego remover la materia sólida para producir una fracción líquida y luego agregar una sal de carbonato a la fracción líquida para ajustar el valor de pH de la fracción líquida de 5.5 a 7.
