Process for producing a phosphate of the lanthanoids, and phosphate produced thereby
摘要：
A process for producing a phosphate of the lanthanoids is described. The process is based on a two-jet precipitation, starting from separate reservoirs of a rare earth salt solution and a phosphate solution which are introduced simultaneously by separate feedlines into an aqueous acidified initial charge with stirring at a pH of 0≦pH≦1. After the solutions are added, the pH is raised to a pH of >2 to complete the phosphate precipitation.

描述了生产镧系元素的磷酸盐的方法。 该方法基于双喷射沉淀，从分开的稀土盐溶液和磷酸盐溶液开始，其通过分开的进料线同时引入含水酸化的初始进料，并在pH = 0〜 1。 加入溶液后，将pH升高至pH> 2，完成磷酸盐沉淀。
