Scandium(CAS: 7440-20-2)

Scandium is a chemical element with the symbol Sc and CAS number 7440-20-2. It is a silvery-white, metallic element with atomic number 21. Scandium is a relatively rare element, and it is often used in alloys to improve strength and heat resistance. Its chemical properties are similar to other elements in group 3 of the periodic table.

Scandium is primarily used in the production of aluminum-scandium alloys for aerospace and sports equipment. It is also used in LED phosphors, making them more efficient and longer-lasting. Additionally, scandium is used in nuclear applications and as an additive in magnesium alloys for high-performance applications.

Scandium is generally considered safe under normal conditions, but it should be handled with care. Exposure to scandium dust or fumes should be minimized, and proper ventilation is recommended. Protective gloves and eyewear should be used when handling scandium compounds. Ingestion or inhalation of high concentrations may cause irritation, and medical attention should be sought if any symptoms occur.

Scandium should be stored in a cool, dry place away from moisture and direct sunlight. It is recommended to store scandium in sealed containers to prevent contamination and oxidation. The storage area should be well-ventilated to avoid the accumulation of flammable gases. If scandium comes into contact with water, it can release hydrogen, so it should be kept in a dry environment to minimize the risk of reaction.
