- Gallium is a soft, silvery-white metal, similar to aluminium. Uses. 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.

Galling Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together.Galling is caused by a combination of friction and adhesion between the surfaces, followed by slipping and tearing of crystal structure beneath the surface.alling is caused by macroscopic transfer of material between metallic surfaces, during transverse motion (sliding). Galling occurs frequently whenever metal surfaces are in contact, sliding against each other, especially with poor lubrication.

- Description: Named from the Latin word for France, gallium is a soft silvery metal with many unusual properties. It is stable in air and water but reacts with acids and alkalis. It has a very low melting point; if gallium is held in one's hand, it will melt.

Gallium Gallium is a chemical element with symbol Ga and atomic number 31. It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and thallium. Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite.

Gallium The melting point of gallium is used as a temperature reference point. The alloy galinstan (68.5% gallium, 21.5% indium, and 10% tin) has an even lower melting point of −19 °C (−2 °F), well below the freezing point of water.allium does not exist in free form in nature, and the few high-gallium minerals such as gallite (CuGaS 2) are too rare to serve as a primary source of the element or its compounds. Its abundance in the Earth's crust is approximately 16.9 ppm.

Tin Tin is a chemical element with symbol Sn (from Latin: stannum) and atomic number 50. It is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons.

Gallium - Melts-in-Your-Hand Metal Check It Out. The chemical element Gallium does not exist in pure form in nature, but since it's so magical and badass looking all solid-to-liquid-at-the-touch-of-a-human-hand and all, of course man figured out a way to extract it from bauxite and zinc ores to use as his personal plaything.

praseodymium A soft, silvery, malleable, ductile rare-earth element that develops a characteristic green tarnish in air. It occurs naturally with other rare earths in monazite and bastnaesite and is used to color glass and ceramics yellow, as a core material for carbon arcs, and in metallic alloys. Atomic number 59; atomic weight 140.908; melting point 931°C; boiling point 3,520°C; specific gravity 6.773; valence 3, 4.

Gallium Gallium reacts with chalcogen elements (sometimes called the oxygen family) only at relatively high temperatures. At room temperature, gallium metal is unreactive towards air and water due to the formation of a passive, protective oxide layer.

- By Richard I. Gibson. Visit this post for a 2013 update on gallium. Gallium, named for France, comes to the US ironically from Germany, while the biggest proportion of imported germanium comes from Belgium. Both elements are byproducts yielded by refining other metals.

- The few minerals which contain substantial percentages of gallium are too rare to serve as a commercially viable source of the element. Gallium is found in small amounts in the aluminum ore bauxite and the zinc ore sphalerite, and is therefore extracted from waste materials from the processing of these metals.

- Bile or gall is a dark green to yellowish brown fluid, produced by the liver of most vertebrates, that aids the digestion of lipids in the small intestine.In humans, bile is produced continuously by the liver (liver bile), and stored and concentrated in the gallbladder (gallbladder bile).he color of bile is often likened to fresh-cut grass, unlike components in the stomach that look greenish yellow or dark yellow. Bile may be forced into the stomach secondary to a weakened valve (pylorus), the presence of certain drugs including alcohol, or powerful muscular contractions and duodenal spasms.

Sci-Toys.com In the photo above, I am holding two small vials of liquid metal. The vial on the right contains gallium, an element that melts at 29.76° Celsius (85.57° Fahrenheit). The vial on the left is an alloy that contains gallium, indium, and tin, and melts at -20° Celsius (-4° Fahrenheit). (Both are available in our catalog .). The gallium is liquid because I had the bottle in my shirt pocket, next to my warm body. At normal comfortable room temperatures it is a solid. Because gallium expands when it solidifies (unlike most metals), the vials are only filled half way. To get the solid metal out of the vial, simply warm it up in a cup of hot water until it melts.
