FAQ

What are the physical and chemical properties of Gadolinium (CAS: 13572-97-9)?

Gadolinium is a rare earth metal with a silvery-white appearance. It has a crystalline structure, a molecular weight of approximately 157.25 g/mol, and a density of 7.9 g/cm³. Gadolinium is highly reactive with chlorine and fluorine, and it can also form complexes with water. It is not particularly soluble in water but dissolves in acids.

How is Gadolinium (CAS: 13572-97-9) typically synthesized?

Gadolinium is typically synthesized through the reduction of gadolinium(III) oxide (Gd2O3) with lanthanum metal. Another method involves the reduction of gadolinium nitrate (Gd(NO3)3) with metallic sodium or potassium. These processes yield gadolinium with high purity and selectivity, suitable for various applications.

What industries use Gadolinium (CAS: 13572-97-9)?

Gadolinium is widely used in the electronics industry for its magnetic properties, making it ideal for use in magnetic alloys and permanent magnets. It is also used in the pharmaceutical industry for MRI contrast agents. Additionally, gadolinium is utilized in nuclear and semiconductor industries for its neutron-absorbing properties and thermal conductivity.

What precautions should be taken when handling Gadolinium (CAS: 13572-97-9)?

Gadolinium should be handled in a well-ventilated area and ideally within a fume hood. Personal protective equipment (PPE) such as gloves, safety goggles, and protective clothing is necessary. Spills should be cleaned up using appropriate methods, and the material safety data sheet (MSDS) should be consulted for specific guidelines on disposal and emergency procedures. Gadolinium is not highly toxic but should be managed carefully due to its reactivity with certain chemicals.
