Application of Dysprosium Oxide
1)Dysprosium oxide serves as the primary precursor for dysprosium metal and finds critical applications across multiple high-tech industries. In magnetism, it significantly enhances neodymium-iron-boron (NdFeB) permanent magnets by improving coercivity and temperature resistance when added at 2-3%, making these magnets essential for electric vehicles and wind turbines.
2)In nuclear technology, dysprosium oxide-nickel cermets are utilized in control rods for nuclear reactors due to dysprosium's exceptional thermal-neutron absorption properties. The electronics industry employs high-purity dysprosium oxide as an antireflection coating in photoelectric devices and in data storage applications.
3)For lighting applications, dysprosium compounds are incorporated into metal halide lamps and as activators in phosphors. As a trivalent luminescent material activator, dysprosium emits both yellow and blue light bands, making dysprosium-doped materials valuable for three-primary-color fluorescent applications.
4)Dysprosium oxide serves as a raw material for Terfenol-D, a magnetostrictive alloy enabling precise mechanical movements in advanced sensors and actuators. The material also finds specialized uses in glass manufacturing, ceramics, laser technologies, and as a component in magneto-optical memory materials including yttrium iron garnet and yttrium aluminum garnet.
The demand for dysprosium oxide has grown significantly with the expansion of clean energy technologies and advanced electronics, elevating its importance as a strategic rare earth material.
Preparation of Dysprosium Oxide : Dysprosium nitrate solution reacts with sodium hydroxide solution to generate dysprosium hydroxide, which is separated and then burned to obtain dysprosium oxide:
Packaging of Dysprosium Oxide：In steel drum with inner double PVC bags containing 50kg net each.
