Dysprosium Oxide, is the main raw materials for Dysprosium Metal which is widely used in Neodymium-Iron-Boron magnets, also have specialized uses in ceramics, glass, phosphors, lasers and Dysprosium Metal halide lamp.
High purity of Dysprosium Oxide is used in electronics industry as an antireflection coating in photoelectric devices.
Because of dysprosium's high thermal-neutron absorption cross-section, Dysprosium-Oxide–Nickel cermets are used in neutron-absorbing control rods in nuclear reactors.
Dysprosium and its compounds are highly susceptible to magnetization, they are employed in various data-storage applications, such as in hard disks.
1. Nuclear reactor: Due to its ability to capture neutrons, it is used as a neutron absorber in nuclear reactors.
2. Magnets: Dysprosium is a key ingredient in the production of high-performance permanent magnets, especially those used in electric vehicles, wind turbines and various electronic devices. Dysprosium enhances the magnetic properties of these materials.
3. Phosphor: Dysprosium oxide is used in phosphors for fluorescent and LED lamps, helping to improve the efficiency and color quality of the emitted light.
4. Glass and Ceramics: Used in the production of certain types of glass and ceramics to improve their properties, such as thermal stability and color.
5. Research and Development: Dysprosium oxide is also used in a variety of research applications, including research in materials science and solid state physics.
Store in a cool, dry and dark place.
1. Container: Store dysprosium oxide in sealed containers made of appropriate materials, such as glass or high-density polyethylene (HDPE) to prevent moisture absorption and contamination.
2. Environment: Keep the storage area dry, cool and well ventilated. Avoid exposure to moisture as this will affect the performance of the material.
3. Temperature: Store at room temperature, away from direct sunlight and heat sources to prevent any degradation or deterioration of the material.
4. Label: Clearly label containers with the chemical name, concentration, and any relevant safety information.
5. Safety Precautions: Please follow appropriate safety guidelines when handling and storing dysprosium oxide, including the use of personal protective equipment (PPE) such as gloves and masks, as inhalation or ingestion of dysprosium oxide may pose health risks.
1. Regulatory Compliance: Ensure compliance with local, national and international regulations regarding the transportation of rare earth materials. This may include specific labeling, documentation and packaging requirements.
2. Packaging: Use appropriate, moisture-proof and contamination-proof packaging materials. The container should be strong and airtight to prevent leakage or spillage during transportation.
3. Label: Clearly label the packaging with the correct chemical name, hazard symbol (if applicable), and handling instructions. Include all necessary safety data sheets (SDS) when shipping.
4. Personal Protective Equipment (PPE): Ensure that personnel handling the cargo wear appropriate PPE, such as gloves and masks, to minimize exposure to dust or particles.
5. Avoid Inhalation: Dysprosium oxide generates dust, so precautions should be taken during handling and transportation to minimize dust generation. Use dust suppression methods, such as wetting the material if appropriate.
6. Transportation conditions: Ensure the transportation environment is stable and avoid extreme temperature and humidity affecting the materials.
7. Emergency Procedures: Develop emergency procedures for accidental releases or exposures during transport. This includes having a spill kit and first aid supplies ready.
1. Inhalation Risk: Dust from dysprosium oxide may be harmful if inhaled. It may cause respiratory irritation or other health problems, so appropriate precautions should be taken to minimize dust exposure.
2. SKIN AND EYE IRRITATION: Dysprosium oxide may cause skin and eye irritation upon contact. It is recommended to use personal protective equipment (PPE) such as gloves and goggles when handling this material.
3. Environmental Impact: Although dysprosium oxide is not classified as hazardous waste, it should still be properly handled and disposed of to prevent environmental pollution.
4. Regulatory Classification: Depending on the jurisdiction, the handling, transportation, and disposal of dysprosium oxide may be subject to specific regulations. Please always check local regulations for compliance.
