Gallium (III) oxide (Ga2O3) is a chemical compound used in vacuum
deposition and as part of the manufacturing of semiconductor
devices. Gallium oxide is a white powder insoluble in water, but
soluble in hot alkalis and acids
Gallium oxide is precipitated in hydrated form upon neutralization
of acidic or basic solution of gallium salt. Also, it is formed on
heating gallium in air or by thermally decomposing gallium nitrate
at 200-250C. It can occur in five different modifications, ,,, and
. Of these modifications -Ga2O3 is the most stable form.
-Ga2O3 is prepared by heating nitrate, acetate, oxalate or other
organic derivatives above 1000C. The -Ga2O3, with a melting point
of 1740C, density is 5.88g/cm3
-Ga2O3 density is 6.44g/cm3. can be obtained by heating -Ga2O3 at
65kbars and 1100C for 1 hour giving a crystalline structure. The
hydrated form can be prepared by decomposing precipitated and
"aged" gallium hydroxide at 500C.
Applications and Uses: Catalyst, Optical Uses, Vacuum deposition as
a chemical intermediate, and in semiconductor electronics,
Nanotechnology , Scanning electron microscopy , Transmission
electron microscopy, Ellipsometry,. Possible uses for Ga2O3 include
piezoelectric resonators and transducers.
Gallium(III) oxide is an important functional material. It has been
studied in the use of lasers, phosphors and luminescent materials,
has been shown to demonstrate catalytic properties and has also
been used as an insulating barrier in tight junctions. The stable
oxide of gallium, monoclinic -Ga2O3, has current applications in
gas sensors and luminescent phosphors and can be applied to
dielectric coatings for solar cells. This stable oxide has also
shown potential for deep-ultraviolet transparent conductive oxides.
It is important to accurately determine the optical functions as
these are essential for device simulations and improvement in
material preparation. The thin Ga2O3 films are of commercial
interest as gas sensitive material and Ga2O3 based glasses are
among the best optical materials used in advanced technologies.
Ellipsometry is a procedure that can be used to determine optical
functions of the -Ga2O3.
-Gallium (III) oxide is also very important in the production of
catalysts . It is needed for the preparation of Ga2O3-Al2O3
catalyst. The preparation of this catalyst involves reacting Al2O3
with aqueous solutions of gallium nitrate, followed by evaporation
to dryness at 393K, and calcining in air (i.e.thermal decomposition
of the compound) for 4 hours at 823K.
