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 200-250˚C. It can occur in five different modifications, α,β,δ,γ and ε. Of these modifications β-Ga2O3 is the most stable form.

β-Ga2O3 is prepared by heating nitrate, acetate, oxalate or other organic derivatives above 1000˚C. The β-Ga2O3, with a melting point of 1740˚C, density is 5.88g/cm3
α-Ga2O3 density is 6.44g/cm3. can be obtained by heating β-Ga2O3 at 65kbars and 1100˚C for 1 hour giving a crystalline structure. The hydrated form can be prepared by decomposing precipitated and "aged" gallium hydroxide at 500˚C.

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 β-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 β-Ga2O3.
β-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.
