Uses of Holmium
As a result of its special magnetic properties, holmium is used in alloys for the production of magnets and as a flux concentrator for high magnetic fields.
Holmia (holmium oxide) is used as a yellow or red coloring for glass and cubic zirconia.
Holmium isotopes are good neutron absorbers and are used in nuclear reactor control rods.
Holmium is also used in solid-state lasers for non-invasive medical procedures treating cancers and kidney stones.
