AB  - This dataset is derived from the research on the production scale of high-purity rare earth oxide reagents at the kilogram level. In response to the problems of limited variety, low purity, and difficulty in deep purification and impurity removal of domestic high-end rare earth oxide and halide reagents, relevant experimental research was creatively carried out, and good results were obtained. Based on the preliminary experiments, a step-by-step method experiment was carried out to optimize the process flow and parameters for kilogram level production. It mainly includes the production process of kilogram level reagents for five high-purity rare earth oxides (high-purity lanthanum oxide, high-purity cerium oxide, high-purity neodymium oxide, high-purity ytterbium oxide, high-purity scandium oxide), testing methods and standards for raw materials, intermediate products, and products, product naming, packaging, and transportation conditions. Provide key technical support for the batch stabilization production of high-purity rare earth oxide reagents.   Due to the special nature of rare earth materials, this dataset is not publicly available and only shares metadata. To obtain the entity of the dataset, please contact the data manager.
