High-purity and ultra-high-purity rare earth products can be made into new materials with multiple functions and are widely used in the preparation of industrial products and cutting-edge defense fields. Among them, rare earth oxides are relatively important rare earth products. Due to their special properties, they can not only be used to prepare industrial products such as luminescent materials, catalysts, glass and ceramics, but also in many cutting-edge fields such as electronics, lasers, nuclear industry, and superconductivity.

The purity of rare earth oxides determines the performance of materials. With the development of science and technology and the improvement of production levels, higher requirements are placed on the purity of rare earth oxides. The purity of rare earth oxides refers to the ratio of the mass of a specific rare earth oxide in a product to the total mass of rare earth oxides in the product, recorded as Re₂O₃/TREO (total mass of rare earth oxides). According to the purity, it can be divided into: low-purity products with a purity not higher than 99%, high-purity products with a purity of 99.9% to 99.99%, and ultra-high-purity products with a purity of 99.999% and above.

At present, the industry mostly uses the extraction method to produce rare earth oxides. This method is suitable for the production of large quantities of ordinary purity rare earth oxides. In order to obtain ultra-high purity rare earth oxide products, extraction resin chromatography or ion membrane exchange method is used for further separation and purification.
