Description

Technical Field

[0001] The utility model belongs to the technical field of terbium oxide filtering, and more specifically, particularly relates to terbium oxide screening and impurity removal equipment. Background Art

[0002] At present, terbium oxide is in powder form and is used as a raw material for making metallic terbium, an additive for glass, and NdFeB permanent magnets. It is also used in metal halide lamps, magneto-optical memory materials, yttrium iron or yttrium aluminum garnet, and the atomic energy industry. Terbium oxide can also be used as an additive for NdFeB permanent magnets. Adding about 2 to 3% of terbium to this magnet can increase its coercive force. In the past, the demand for terbium was not large, but with the increase in demand for NdFeB magnets, it has become a necessary additive element, and the grade must be around 95 to 99.9%. The demand is also increasing rapidly. Terbium oxide is also used as a raw material for making metallic terbium, an additive for glass, and NdFeB permanent magnets. It is also used in metal halide lamps, magneto-optical memory materials, yttrium iron or yttrium aluminum garnet, and the atomic energy industry.

[0003] During the processing of terbium oxide, in order to ensure the overall purity of terbium oxide, it is necessary to filter and screen the terbium oxide to separate some internal impurities from the main body so as to obtain pure terbium oxide.

During the filtration process, terbium oxide is easily exposed to air, which can easily make the terbium oxide wet and agglomerated, further increasing the difficulty of filtering and recovering terbium oxide.
