Cerium, as a rare earth element, has an extremely wide range of applications. It can be used as a grinding material, oxygen sensor, solid electrolyte, ultraviolet absorber, catalyst, pigment, polishing material, and metal material additive. However, in the field of chip grinding, high-purity cerium carbonate is required as a raw material. In addition to the high requirements for rare earth impurities in cerium carbonate, there are also extremely high requirements for non-rare earth impurities such as iron and alkali metals. |
