Holmium (Ho) Nanoparticles - Properties, Applications

Nanoparticles have a potentially vast area of application from high-tech industries to biomedical fields. They are known to possess excellent catalytic, optical, magnetic, and electronic properties.

Holmium is a Block F, Period 6 element. It is a rare earth element that is relatively soft and malleable. It possesses the highest magnetic moment of any naturally occurring element. It is found in minerals such as gadolinite and monazite. The morphology of these particles is spherical, and they appear as a black powder.

Holmium nanoparticles are graded as flammable solids.
