- Gallium is a
chemical element that has the symbol Ga and atomic number 31.
- A soft silvery
metallic poor metal, gallium is a brittle solid at low temperatures but
liquefies slightly above room temperature and will melt in the hand.
- It occurs in trace
amounts in bauxite and zinc ores.
- Gallium does not
exist in free form in nature, nor do any high-gallium minerals exist to
serve as a primary source of extraction of the element or its
compounds.
- Gallium melts near
room temperature and has one of the largest liquid ranges of any metal,
so it has found use in high temperature thermometers.
- Most gallium is
extracted from the crude aluminium hydroxide solution of the Bayer
process for producing alumina and aluminium.
- An important
application is in the compounds gallium nitride and gallium arsenide,
used as a semiconductor, most notably in light-emitting diodes
(LEDs)
- Gallium has been
used as a component in low-melting alloys for signal devices.
- Liquid gallium
reflects 88% of incident light, the solid metal - just slightly less, so
gallium is very useful in mirrors production, the glass surface of which
may be just brushed by gallium.
- The widebandgap
semiconductor families, which include GaN, silicon carbide (SiC) and
diamond, have long been touted for their potential superior performance
in high-frequency and/or high-power applications.
- Gallium compound is
used in the production of several electronic parts such as diodes and
transistors, made for voltage rectification, signal amplification,
etc.
- The pyrolysis of
organometallic precursors has already been demonstrated to be a powerful
route to the synthesis of nanotubes and filled nanotubes.
- Solvent extraction
is a very effective method for the separation and concentration of metal
cations, including the Group 13 metals, in solution.
- As a
crystallographic approach to evaluate the extraction mechanism of Ga3+
with H3tdmba and the chemical structure of the extracted Ga3+, crystal
structure of H3tdmba4 was analyzed by using X-ray
crystallography.
- The average
coordination number for a-GaN is thus calculated to be 3.43, slightly
less than the value of 4.00 for crystalline GaN.
- A solvent extraction
process based on aqueous nitric acid and organic tri-butyl phosphate
(TBP) has been suggested as a fully developed method for separating
gallium from the plutonium.
- The market forecast
for both gallium nitride based optoelectronic and electronic devices is
projected to grow to nearly $1.3 billion in 2004, and to more than $4.8
billion in 2009, compared with $420 million in 1999.
- GaN-based blue LEDs
by Nichia and Toyoda Gosei in late 1993, a robust worldwide market for
these devices has developed.
- In a little over six
years, the market has grown from virtually nothing to $420 million in
1999.
- Blue laser diodes
will begin to be used in high-density DVD drives in 2002 and to capture
a large share of the optical storage market in subsequent years.
- The electronic
device market is forecast to begin in 2002 with modest shipments of
RF/microwave and high-temperature devices, and to expand in subsequent
years to include power switches, power rectifiers and high-voltage
rectifiers.
