FAQ

What are the physical and chemical properties of Yttrium (CAS: 13598-57-7)?

Yttrium (CAS: 13598-57-7) is a lustrous, silvery-white, malleable, and ductile rare-earth metal. It has a cubic close-packed crystal structure and a high melting point of 1522°C. Its atomic weight is approximately 88.906. Yttrium is relatively stable in air but reacts with water and halogens, forming yttrium hydroxide and yttrium halides. It has good thermal and electrical conductivity. Yttrium is slightly soluble in dilute acids but insoluble in alkalis.

How is Yttrium (CAS: 13598-57-7) typically synthesized?

Yttrium is typically synthesized through the reduction of yttrium oxide or yttrium fluoride with metallic calcium or magnesium. Other methods include reaction of yttrium tri-chloride with metallic sodium or potassium, and reduction of yttrium oxide with hydrogen. The purity of the product depends on the method and conditions used, with high-purity yttrium being produced through electrolysis or vacuum melting.

What industries use Yttrium (CAS: 13598-57-7)?

Yttrium (CAS: 13598-57-7) is used in a variety of industries. It is a key component in the production of yttrium-aluminum-garnet (YAG) and yttrium iron garnet (YIG) ceramics, which are used in high-intensity lighting, lasers, and magnetic materials. Yttrium is also used in phosphors for television and computer monitors, in solid-state devices, and as a dopant in semiconductor materials. Additionally, it is used in catalytic converters and in the production of yttrium-based superconductors.

What precautions should be taken when handling Yttrium (CAS: 13598-57-7)?

When handling Yttrium (CAS: 13598-57-7), appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat should be worn. Yttrium is not particularly hazardous, but it can ignite spontaneously in air. It should be stored in a dry, well-ventilated area away from flammable materials. In case of spill, it should be handled using appropriate containment methods, and the spill area should be cleaned thoroughly. Always refer to the Safety Data Sheet (SDS) for detailed handling procedures and emergency response information.
