dysprosium metal
Dysprosium is a silver-white metal, soft and can be cut
with a knife; the melting point is 1412°C, the boiling point is 2562°C,
and the density is 8.55 g/cm3; it has superconductivity near absolute
zero. Dysprosium is quite stable in the air, and is easily oxidized by
air and water at high temperatures to form Dysprosium trioxide.
Dysprosium is mainly used to make dysprosium lamps as a new type of
lighting source; Dysprosium can be used as a reactor control material;
Dysprosium compounds can be used as catalysts in the oil refining
industry.
Silver white rare earth metal. Hard and lively. It is easily oxidized by
oxygen, reacts quickly with water, and dissolves in acid. Alloys used to
make magnets, infrared generating equipment, laser materials and atomic
energy industry.
The main uses of Dysprosium are:
(1) Used as an additive for neodymium iron boron permanent magnets.
Adding about 2 to 3% dysprosium to this magnet can increase its
coercivity. In the past, the demand for dysprosium was not large, but
with the use of neodymium iron boron magnets As the demand increases, it
becomes a necessary additional element, and the grade must be around
95-99.9%, and the demand is also increasing rapidly.
(2) Dysprosium is used as phosphor activator, trivalent dysprosium is a
promising single-luminescence center three-primary color luminescent
material activated ion, it is mainly composed of two emission bands, one
is yellow light emission, the other is blue light Emitting,
dysprosium-doped luminescent materials can be used as three primary
color phosphors.
(3) Dysprosium is a necessary metal raw material for the preparation of
the large magnetostrictive alloy terbium and dysprosium (Terfenol)
alloy, which can realize the precise activities of some mechanical
movements.
(4) Dysprosium metal can be used as magneto-optical storage material,
with high recording speed and reading sensitivity.
(5) For the preparation of dysprosium lamps, the working substance used
in dysprosium lamps is dysprosium iodide. This kind of lamp has the
advantages of large brightness, good color, high color temperature,
small volume, stable arc, etc., and has been used in movies and printing
Wait for the lighting source.
(6) Due to the large cross-sectional area of neutron capture, dysprosium
is used in the atomic energy industry to measure the neutron spectrum or
as a neutron absorber.
(7) Dy3Al5O12 can also be used as a magnetic working material for
magnetic refrigeration. With the development of science and technology,
the application fields of Dysprosium will continue to expand and
extend..
