- Holmium was discovered by Delafontaine and
Soret in 1878 AD. It is a soft silvery metallic element, which is found
in the lanthanide
series of inner transition metals in Group III a
of the periodic table.
- Holmium occurs with the rare earths in
their ores. It is separated from other rare earths by ion exchange
chromatography. It is prepared by reducing the anhydrous chloride with
calcium .which is stable in air. It has unusual magnetic properties. It
is used in the filters used for the calibration of the wavelength
settings in UV spectrophotometers.
- It is usually commercially extracted from
monazite using ion exchange techniques. Its compounds in nature, and in
nearly all of its laboratory chemistry, are trivalently oxidized,
containing Ho(III) ions. Trivalent holmium ions have fluorescent
properties similar to many other rare earth ions (while yielding their
own set of unique emission light lines), and holmium ions are thus used
in the same way as some other rare earths in certain laser and glass
colorant applications.
- Holmium has the highest magnetic strength
of any element and therefore is used for the pole pieces of the
strongest static magnets.
Because holmium strongly absorbs neutrons,
it is also used in nuclear control rods.
- Holmium has the highest magnetic moment
(10.6 µB) of any naturally occurring element and possesses other unusual
magnetic properties. When combined with yttrium, it forms highly
magnetic compounds.
- Holmium is not naturally found as a free
element. It does occur combined with other elements in gadolinite,
monazite, and other rare-earth minerals. The main mining areas are
China, United States, Brazil, India, Sri Lanka, and Australia with
reserves of holmium estimated as
400,000 tonnes.
- Holmium is one of the colorants used for
cubic zirconia and glass, providing yellow or red coloring. Glass
containing holmium oxide and
holmium oxide solutions have
sharp optical absorption peaks in the spectral range 200–900 nm.
therefore used as a calibration standard for optical
spectrophotometers.
- The radioactive but long-lived
Ho-166m1 is used in calibration of gamma ray spectrometers
