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.
