FAQ

What is Dysprosium (CAS: 7429-91-6)?

Dysprosium is a chemical element with the symbol Dy and CAS number 7429-91-6. It is a rare earth metal with a silvery-white appearance and a melting point of 1,412°C. Dysprosium is magnetic at room temperature and is used in various applications due to its magnetic and thermal properties.

What are the main uses of Dysprosium (CAS: 7429-91-6)?

Dysprosium is primarily used in the production of dysprosium neodymium magnets, which are crucial for electric vehicles and wind turbines. It is also used in lasers, optical devices, and as a neutron absorber in nuclear reactors.

Is Dysprosium (CAS: 7429-91-6) safe?

Dysprosium is generally considered safe under normal usage conditions. However, it is important to handle it with care, as it can release dust that may cause irritation. Protective equipment, such as gloves and masks, should be worn during handling to avoid inhalation and skin contact.

How should Dysprosium (CAS: 7429-91-6) be stored?

Dysprosium should be stored in a cool, dry place away from direct sunlight and moisture. It should be kept in a tightly sealed container to prevent oxidation. Avoid contact with water and organic materials, as it is highly reactive with water and can ignite spontaneously in air. Do not store near flammable materials or oxidizers.
