[0002] There are 17 kinds of rare earth elements, and their chemical properties are very similar, so purification is very difficult. Common separation methods in industry include solvent extraction, graded precipitation, graded crystallization, ion exchange, etc. Terbium oxide, also known as terbium oxide (III, IV), is an inorganic chemical product with a molecular formula of O7Tb4 and a molecular weight of 747.6972. It is used as a phosphor. Especially for X-ray fluorescent screens. According to the main lattice, terbium emits green or blue. The existing terbium oxide is extracted from the original ore, which requires grinding, dissolving and extraction of the original ore. At the same time, it requires the use of more equipment and supporting processes to complete. The materials need to be transferred between the processes, resulting in low production efficiency and easy intermediate pollution. Utility Model Content
