Terbium metal
Terbium is a member of the lanthanide series, atomic number
65, periodic group III (class) subgroup, lanthanide element, soft and
malleable silver-white metal, easy to be corroded by air at high
temperature; very corrosive at room temperature slow. It is soluble in
acid and colorless in salts. The oxide Tb4O7 is brown. , Element symbol
Tb, belongs to rare earth metal, toxic. There is only one stable isotope
in nature, and there are 20 other radioactive isotopes. The hexagonal
crystal lattice is soluble in dilute acid and reacts slowly with water.
Has high reactivity. It should be stored in a container filled with
inert gas or a vacuum container.
Its compounds can be used as insecticides and also used to treat skin
diseases. The preciousness of terbium and its many excellent
characteristics make it in an irreplaceable position in some application
fields. It is widely used in agriculture, industry, animal husbandry,
medicine and health, high-tech industries and other fields
Application areaedit
Medical treatment: X-ray photography used to diagnose human bones and
lungs must use terbium. In order to improve the sensitivity of X-ray
film, a sensitizer that can emit fluorescence when exposed to X-rays is
needed. Tb3+ is used in the sensitizer Gd2O2S, which improves the
sensitivity of the film.
Magnetic deflection: The material stretches in the direction of
magnetization, that is, the change in size is called magnetic
deflection, also called magnetic distortion. Terbium-iron and
terbium-dysprosium-iron have a large magnetic deflection effect and are
used in the print head of computer printers and precision processing
equipment. The secret lies in the shape of the flat 4f electron cloud of
terbium, and after applying a magnetic field, in order to move the
electrons, it relies on the movement of surrounding atoms that
correspond to it.
Activator: Phosphors are used as the activator of the green powder in
the three primary color phosphors, such as terbium-activated phosphate
matrix, terbium-activated silicate matrix, terbium-activated
cerium-magnesium aluminate matrix, all in the excited state Glows green
light.
Optical disk: As a computer recording medium, the optical disk uses a
heavy rare earth element-transition metal element series alloy
represented by a terbium-iron-cobalt alloy. During laser irradiation,
information is written and read using changes in reflected light
magnetized by the surface.
Magneto-optical storage materials and terbium-based magneto-optical
materials have reached the scale of mass production. Magneto-optical
optical discs developed with Tb-Fe amorphous thin films are used as
computer storage elements, and the storage capacity is increased by 10
to 15 times.
Magneto-optical glass: Faraday rotator glass containing terbium is a key
material for manufacturing rotators, isolators and circulators widely
used in laser technology. Especially the development of terbium and
dysprosium magnetostrictive alloy (TerFenol)
.
