Beschreibung
Zusammenfassung:	The invention discloses a production technique of granular crystal cerous nitrate products. A cerous nitrate solution is treated, concentrated, cooled by a changed way, dehydrated by a centrifuge, and then granular crystal cerous nitrate products with fewer impurities and higher purity are obtained, wherein the non-rare-earth impurities is fewer, for example, the content of MgO is smaller than 2ppm, the content of MnO is smaller than 20ppm, and the content of Fe2O3 is smaller than 20ppm.
