In its pure form gallium is an unusual element to say the least With a melting point of approximately 30C gallium is a liquid at just above room temperature When alloyed with other elements (notably indium) the resulting melting point is below room temperature
Gallium you see melts at 30 o C which means that on a hot day you hold it in your pocket at your peril Surprisingly however it's not very volatile In fact Gallium has the largest liquid range of any material known to man Its boiling point is just over 2400 o C So unlike other liquid metals there is no toxic vapour to worry about
Many elements in group II and group III on the periodic table combine with arsenic to produce arsenide semiconductors Gallium Arsenide is the most common of these and it is utilized in manufacture of devices such as monolithic microwave integrated circuits microwave frequency integrated circuits laser diodes solar cells LEDs optical windows etc
Indium forms an alloy with gallium that is liquid at room temperature and is fairly non-toxic This would be a great substitute for mercury except it sticks to everything and stains hands which means you can't really touch it either
It is near the non-metallic elements and therefore the bonding is somewhat directional This characteristic makes cross slip easy which is simply the slip changing from one plane to another However like most other FCC metals this can be changed by work hardening at cold temperatures
Gallium is a by-product of aluminum extracted during the processing of bauxite into alumina It can also occasionally be found in Zn ore We are a refiner and supplier of gallium materials Indium Corporation supplies gallium In the form of shot and ingot In the form of sputtering targets after being alloyed with other elements (Cu-Ga Cu-In-Ga)
Indium and gallium are metals of low abundance in the Earth's crust with typical concentrations of 0 11–0 25 mg/L indium and 15–19 mg/L gallium [1 2] These two chemical elements were of only minor technical relevance in the past

Many elements in group II and group III on the periodic table combine with arsenic to produce arsenide semiconductors Gallium Arsenide is the most common of these and it is utilized in manufacture of devices such as monolithic microwave integrated circuits microwave frequency integrated circuits laser diodes solar cells LEDs optical
Indium (atomic number 49 symbol In) is a malleable and soft chemical element which is similar to thallium and gallium in terms of chemical properties It is a rare and fusible metal and exhibits intermediary properties between gallium and thallium The primary source of indium is zinc ores and it occurs in a compound form in them
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B) as well as the metals aluminum (Al) gallium (Ga) indium (In) and thallium (Tl) Boron forms mostly covalent bonds while the other elements in Group 3A form mostly ionic bonds
Indium gallium arsenide's wiki Indium gallium arsenide (InGaAs) (alternatively gallium indium arsenide) is a ternary alloy (chemical compound) of indium gallium and arsenic Indium and gallium are both from boron group (group III) of elements while arsenic is a pnictogen (group V) element Thus alloys made of these chemical groups are referred to as III-V compounds
This very soft indium foil is used to create seals between glass components in high-vacuum systems The indium is soft enough to deform into any pits and irregularities in the glass just like a rubber seal would But unlike rubber indium doesn't give off all sorts of vapors and leak like a sieve
Indium metal gives off a high-pitched scream when bent Similar to the tin cry this scream sounds more like a crackling sound Indium is similar to gallium in that it readily wets glass and is very useful for making low-melting alloys An alloy consisting of 24 percent indium and 76 percent gallium is liquid
element 49 Indium was discovered in 1863 by German chemists Ferdinand Reich and Hieronymus Theodor Richter They were researching Thallium and came across indigo streaks that were not known to be present in Thallium They realized that it was a new element and named it Indium

Gallium With the Group 15 (Va) elements nitrogen phosphorus arsenic and antimony and the Group 13 elements aluminum and indium gallium forms compounds—e g gallium nitride GaN gallium arsenide GaAs and indium gallium arsenide phosphide InGaAsP—that have valuable semiconductor and optoelectronic properties
Amorphous Indium Gallium Zinc Oxide Thin-Film Transistors Non-volatile Memory and Circuits for Transparent Electronics The purpose of this dissertation is to develop amorphous oxide semiconductors by pulsed laser deposition show their suitability for TFT applications and demonstrate other classes of devices such as non-volatile memory elements
Indium is an ingredient in the gallium–indium–tin alloy galinstan which is liquid at room temperature and replaces mercury in some thermometers Other alloys of indium with bismuth cadmium lead and tin which have higher but still low melting points (between 50 and 100 C) are used in fire sprinkler systems and heat regulators
scenario for stable mine production of indium and gallium Indium and gallium recycling specialist and expensive Due to indium and gallium production being a by-product of processing ores a growing global industry has arisen to recover the metals either in a spent form from manufacturing processes or from recycling indium- and gallium-bearing
Indium (In) chemical element rare metal of main Group 13 (IIIa or boron group) of the periodic table Indium has a brilliant silvery-white lustre It was discovered (1863) by German chemists Ferdinand Reich and Hieronymus Theodor Richter while they were examining zinc ore samples
Indium radii of atoms and ions One measure of size is the element-element distance within the element It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O 2 is short because of the the double bond connecting the two atoms

May 11 2019Organometallic compounds of gallium and indium Trialkylgallium compounds are mild Lewis acids so the corresponding metathesis reaction in ether produces the complex (C 2 H 5 ) 2 OGa(C 2 H 5 ) 3 Similarly excess use of C 2 H 5 Li leads to the salt Li[Ga(C 2 H 5 ) 4 ]
