Gallium arsenide has a similar structure to silicon and is a useful silicon substitute for the electronics industry. It is an important component of many semiconductors. It is also used in red LEDs (light emitting diodes) because of its ability to convert electricity to light. Solar panels on the Mars Exploration Rover contained gallium arsenide.

Indium Corporation sells compounds based on the elements indium, germanium, gallium, and tin. These compounds are used in the manufacturing process of a number of high-tech devices, as these elements serve as crucial building blocks in semiconductor chips, electronic components, batteries, and other complex electronic products.
For example, some aircraft parts are made of alloys that contain indium. The indium prevents them from wearing out or reacting with oxygen in the air. Alloys and compounds of indium are also used in making optical …
In its compounds, gallium occurs mainly in the +3 oxidation state, and rarely in the +1 oxidation state. Besides the normal salts formed with halogens, chalcogens, etc., gallium easily forms organogallium compounds. Alkylgalliums are liquids at room temperature and quite flammable. Pure gallium metal costs about US$0.40 per gram.
Bayer liquors contain 70–150 mg L −1 of Ga, and three types of extraction process are usually fractional precipitation, electrolytic processes, and extraction with chelating agents. Gallium in the aluminum industry can also be recovered in by-products, such as red mud, electrostatic precipitation dust, and scrubber dust [21, 22].

Isolation and purification of gallium metal. At 19 ppm gallium (L. Gallia, France) is about as abundant as nitrogen, lithium and lead; it is twice as abundant as boron (9 ppm), but is more difficult to extract due to the lack of any major gallium-containing ore.Gallium always occurs in association either with zinc or germanium, its neighbors in the periodic table, or with …
Thin films of indium gallium nitride compounds (In x Ga 1 − x N, simply referred to as InGaN in the following) are usually deposited by metal-organic chemical vapor deposition (MOCVD) or by molecular beam epitaxy (MBE), with the occasional assistance of a remote plasma to produce nitrogen radicals ("Plasma-Assisted MBE"—PAMBE). These …

No headers. The boron family contains elements in group 13 of the periodic talbe and include the semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Aluminum, gallium, indium, and thallium have three electrons in their outermost shell (a full s orbital and one electron in the p orbital) with the valence …
Indium gallium nitride (In x Ga 1−x N) is an ideal material candidate with theoretic efficiencies over 60 pct for multi-junction cells as its range of band gaps covers the solar spectrum: about 0.7 eV for InN [ 8 – 15] to 3.4 eV for GaN [ 16 – 26] depending on the relative indium content, x.
We offer over 220 alloys with melting temperatures ranging from 7–1,064°C. Our products are focused on six main alloy families: gallium (Ga), bismuth (Bi), indium (In), tin (Sn), lead (Pb), and gold (Au).

Many of these alloys contain Pb and Cd, but you still have a few choices if you're looking for an alloy without lead or cadmium in this ...
Gallium is of little use as a structural metal, but its value in many modern electronic devices cannot be understated. Commercial uses of gallium developed from the initial research on light-emitting diodes (LEDs) and III-V radio frequency (RF) semiconductor technology, which began in the early 1950s. In 1962, IBM physicist J.B. Gunn's research ...
6. Dental Amalgams. Owing to their non-toxicity and ability to sustain a wide range of temperatures gallium alloys are also seen as a promising option to replace dental amalgams made of mercury, as mercury is considered toxic for humans. However, this proposal is yet to get acceptance. 7.
The first progress for Copper Indium Gallium Selenide (CIGS) thin-film solar cells was made in 1981 when the Boeing company created a Copper Indium Selenide (CuInSe2 or CIS) solar cell with a 9.4% efficiency, but the CIS thin-film solar cell was synthesized in 1953 by Hahn, H.
