Gadolinium

Description:

Gadolinium is a silvery-white, malleable, and ductile rare earth metal, classified under the lanthanide series of the periodic table. It has the atomic number 64 and is known for its unique magnetic properties, particularly its ability to become ferromagnetic at room temperature, which is relatively rare among the lanthanides. Gadolinium is highly reactive, especially in powdered form, and can oxidize quickly when exposed to air, forming a protective oxide layer. It has a high melting point and is often used in various applications, including in magnetic resonance imaging (MRI) as a contrast agent due to its paramagnetic properties. Additionally, gadolinium compounds are utilized in neutron capture applications and as phosphors in certain types of screens. The metal is typically obtained from minerals such as bastnäsite and monazite and is often processed through complex extraction methods. Safety precautions are necessary when handling gadolinium and its compounds, as they can be toxic in certain forms and concentrations.
