Description:
Lanthanum Metal is silver lump. It is used as
additive for special steel Non-feric Alloy, Hydrogen Storage Alloy,
also as reducer for making other Rare Earth
metal.
Lanthanum is a chemical element with the symbol
La and atomic number *7. Lanthanum is a silvery white metallic
element that belongs to group 3 of the periodic table and is the
first element of the lanthanide series. It is found in some
rare-earth minerals, usually in combination with cerium and other
rare earth elements. Lanthanum is a malleable, ductile, and soft
metal that oxidizes rapidly when exposed to air. It is produced
from the minerals monazite and bastnäsite using a complex
multistage extraction process. Lanthanum compounds have numerous
applications as catalysts, additives in glass, carbon lighting for
studio lighting and projection, ignition elements in lighters and
torches, electron cathodes, scintillators, and
others.
Physical properties
ÂÂ
Lanthanum is a soft, malleable, silvery white
metal which has hexagonal crystal structure at room temperature. At
**0 °C, lanthanum changes to a face-centered cubic structure, and
at **5 °C into a body-centered cubic structure. Lanthanum is
easily oxidized (a centimeter-sized sample will completely oxidize
within a year) and is therefore used in elemental form only for
research purposes. For example, single Lanthanum atoms have been
isolated by implanting them into fullerene molecules. If carbon
nanotubes are filled with those lanthanum-encapsulated fullerenes
and annealed, metallic nanochains of lanthanum are produced inside
carbon nanotubes.
