Indium has been called a "metal vitamin" in alloys. That means that very small amounts of indium can make big changes in an alloy. For example, very small amounts of indium are sometimes added to gold and platinum alloys to make them much harder. Such alloys are used …
Indium is produced mainly from residues generated during zinc ore processing. It was named after the indigo line in its atomic spectrum. The first large-scale application for indium was as a coating for bearings in high-performance aircraft engines during World War II. Afterwards, production gradually increased as new uses were found in fusible alloys, solders, and electronics.

was not until World War II that indium was used in its ﬁrst large-scale application as a coating for bearings in high-performance aircraft engines (Carlin, 1985; Slattery, 1995). Indium increased hardness and helped prevent seizure and corrosion of the bearings.
The name indium was given to the novel element for its indigo blue line in its spectrum. Its symbol is In. Pure indium was isolated in 1864 . In its early days, indium was used as a coating agent of bearing of aircraft engines in World War II. In 1950, indium beads were used in junction transistors. Indium
Another important use of indium is in making alloys - used in electronic devices and dental materials. Indium has been called a "metal vitamin" in alloys, which means that very small amounts of indium can make big changes in an alloy. For instance, the addition of small amounts of indium to gold and platinum alloys makes them much harder.
Discovered in the late 1800s, the element indium was given its name because of the violet light it produced on the spectrum. This lesson explains how indium is used within our world, especially ...
It has a low melting point and is used in making low melting alloys for safety devices and solders. Indium, like gallium, remains a liquid over a large temperature range. Some indium compounds are used in transistors, photoconductors, photocells and thermistors. Indium has the odd property of producing a high-pitched scream when bent.
Indium is chemically similar to both gallium and thallium. It is often used in an alloy with other metals such as tin, aluminium and gold. So how is Indium used in the modern world today? Read on to find out. Uses of Indium. Indium oxide and Indium tin oxide are used as transparent conductive coatings.
Indium and Indiumease has been tested for safety and Indium and Indiumease is the safest of trace minerals. Indium and Indiumease normalizes the master glands and improves athletic performance. Indium and Indiumease may help athletes break speed, power and endurance records. Indium and Indiumease may decrease drug, chemical and alcohol toxicity.
Almost all of the world's indium comes from zinc mines; there are no dedicated indium mines, because it occurs in such small amounts mining for it is impractical. So if demand for zinc declines ...
For over 100 years following its discovery, indium lay in obscurity perceived as uninteresting and of little use. Today, however, this metal is vital to the world economy in the form of indium tin oxide (ITO), which is used in the growing flat- screen TV and solar panel markets.
Indium also is used to measure the thermal neutron flux of nuclear reactors and to monitor neutrons for the protection of personnel and equipment. Natural indium is a mixture of two isotopes: indium-113 (4.28 percent) and indium-115 (95.72 percent).
In a world where global communications are increasingly essential, only one company connects everyone to the things that matter most, from pole to pole. Iridium is a satellite communications company that offers voice and data connectivity anywhere in the world.
Gallium discovery, atomic structure, and location information. There are also tutorials on the first thirty-six elements of the periodic table. GAL-LI-UM. Gallium is one of those elements that is used in industry every day. You have probably never even heard of the element.
About 4 million troy ounces of indium are now produced annually in the Free World. Canada is presently producing more than 1,000,000 troy ounces annually. Sources. Indium is most frequently associated with zinc materials, and it is from these that most commercial indium is now obtained; however, it is also found in iron, lead, and copper ores ...
Indium is commonly used to make alloys and is often referred to as the "metal vitamin," meaning that tiny levels of indium can make a drastic difference in an alloy, according to the RSC.
Mar 29, 2016· Indium is unusual because it is the softest metal that you can actually hold in your hands. Lithium is softer that indium, but because of its high activity, lithium will form caustic alkali in ...
A Indium nitride, antimonide and phosphide are semiconductors used in transistors and microchips. The Indium metal is plated to glass to form atmospheric corrosion-resistant mirror surface that can be used to give a mirror finish to windows of tall buildings, and as a protective film on welders' goggles.
Indium wire is used as a vacuum seal and a thermal conductor in cryogenics and ultra-high-vacuum applications, in such manufacturing applications as gaskets that deform to fill gaps. Indium is an ingredient in the gallium–indium–tin alloy galinstan, which is liquid at room temperature and replaces mercury in some thermometers.
Jul 12, 2013· Great explanation of basic touch screen technology. Indium Tin Oxide (ITO) in Touch Screens. Indium Tin Oxide (or tin-doped indium oxide) is particularly important to the world's dominant smart phone and tablet manufacturers because of its unique material properties perfect for …
Indium can be used to make mirrors that are as reflective as silver mirrors but do not tarnish as quickly. Indium is also used to make low melting alloys. An alloy of 24% indium and 76% gallium is a liquid at room temperature. Estimated Crustal Abundance: 2.5×10-1 milligrams per kilogram.
That's because indium tin oxide, or ITO, is a transparent conducting oxide – or perhaps I should say THE transparent conducting oxide, as it is by far the most widely used. The transparency means you can't see it when it is present as a thin film on the glass screen of your device, and the conducting part is what makes the touchscreen work.
