Gallium and gallium compounds

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. 

Gallium and gallium compounds

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.
