Nanomaterials are gaining in popularity as they can be applied across a wide range of high-tech industries and advanced technologies due to their excellent catalytic, optical, magnetic, and electronic properties.
Gadolinium is a Block F, Period 6 element. It is found in minerals such as monazite and bastnasite. It is malleable and ductile rare-earth metal. The morphology of these particles is spherical, and they appear as a black powder.
Gadolinium nanoparticles are graded as toxic, and when in contact with water, they release flammable gases which can ignite spontaneously.
The chemical properties of gadolinium nanoparticles are outlined in the following table.
