Gallium has received much attention in relation to its application in the production 

of semiconducting compounds. Of these, the most important are the compounds 

of gallium with antimony, arsenic or phosphor. Gallium arsenide (GaAs) is used in 

the production of diodes and transistors for voltage rectification and signal 

amplification. Other gallium arsenide applications include semiconductor "lasing" 

and microwave generation. Gallium is also used in sensors to measure 

temperature, light or magnetic field.  High Purity (99.999%) Gallium Oxide 

(Ga2O3) Powder Elemental or metallic forms of gallium include pellets for 

evaporation source material purposes. Gallium oxide is available in forms 

including powders and dense pellets for use as optical coating and thin film 

applications.Oxides tend to be insoluble. Gallium fluoride is another insoluble form 

for uses in which oxygen is undesirable such as metallurgy, chemical and physical 

vapor deposition and in some optical coatings. Gallium is available in soluble 

forms including chlorides, nitrates and acetates. These compounds can be 

manufactured as solutions at specified stoichiometries.
