TY - Data T1 - Dataset of Preparation Process for High-purity Rare Earth Halide-like Compounds A1 - shi ya nan PY - 2026 DA - 2026-05-19 PB - National Cryosphere Desert Data Center AB - In response to the problems of limited variety, low purity, and difficulty in deep purification and impurity removal of domestic high-end rare earth halide reagents, this study systematically investigates the mass transfer mechanism and deep purification and impurity removal technology of key impurity elements in the deep purification and impurity removal process of rare earth halides, and forms a kilogram scale preparation capability. A preparation process for high-purity rare earth halide oxides was developed using high-temperature hydrolysis oxidation method, resulting in the formation of halide like YbOCl. Based on laboratory preparation technology, further exploration of kilogram scale preparation technology was carried out, and the construction and commissioning of a high-purity anhydrous halide reagent kilogram scale production line were completed. A high-purity rare earth halide and halide reagent kilogram scale process was developed, and kilogram scale process documents were established. The purity index of kilogram scale products met the requirements of the index. Due to the special nature of rare earth materials, this dataset is not publicly available and only shares metadata.
