FARMINGTON, Conn., Dec. 20, 2012 /PRNewswire-iReach/ -- The metal powder manufacturing industry is estimated to be worth $6.6 billion. Together the top six or seven companies that are well established in this field make up roughly one-third of the market--the remaining two-thirds being comprised of small and medium-sized companies spread across various countries. In terms of geographical distribution, the U.S. continues to claim a high proportion of the total volume of powder metal production...

Northwestern´s McCormick School of Engineering Researchers combine computational and experimental methods to understand the arrangement of atoms in solids Understanding the arrangement of atoms in a solid – one of solids´ fundamental properties – is vital to advanced materials research. For decades, two camps of researchers have been working to develop methods to understand these so-called crystal structures. “Solution” methods, championed by...

Violent Collision Created Rare Meteorite

April Flowers for redOrbit.com - Your Universe Online Some meteorites found on Earth contain strikingly beautiful, translucent, olive-green crystals embedded in an iron-nickel matrix. These "space gems," called pallasites, are only found in a tiny fraction of the total number of meteorites, but they have fascinated scientists since they were first identified as originating in outer space more than 200 years ago. A new study, published in the journal Science and led by John Tarduno at...

Amphibole defines an important group of dark-colored rock-forming inosilicate minerals composed of double chain SiO4 tetrahedra linked at the vertices and generally containing ions of iron and/ or magnesium in their structures. In chemical composition and general characteristics they are very similar to the pyroxenes and, like them, fall into three series according to their system of crystallization. The chief difference between amphiboles and pyroxenes is in cleavage: amphiboles form oblique...

Aragonite is a polymorph of the mineral calcite, both having the chemical composition CaCO3. Its structure differs from calcite and leads to a different crystal shape, an orthorhombic system with acicular crystals. By repeated twinning pseudo-hexagonal forms result. It may be columnar or fibrous, occasionally in branching stalactitic forms called flos-ferri (flowers of iron) from their association with the ores at the Carthinian iron mines. The type location for aragonite is Molina de...

The mineral kyanite is an aluminium silicate of the sillimanite group (along with andalusite and sillimanite), also called alumino-silicate. It has the formula Al2O3·SiO2 (Al2SiO5). Its hardness varies widely depending on its crystallographic direction, from 5 to 7.5, and it has a specific gravity of 3.56-3.67. It is translucent, usually blue, but possibly white, gray, green, or black. It is usually found in long-bladed crystals or columnar to fibrous structures. Kyanite is used in...

Limonite Limonite is a ferric hydrate of varying composition, the generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as Limonite often contains a varying amount of oxide compared to hydroxide. Together with hematite, it is mined as ore for the production of iron. Limonite is heavy and yellowish-brown. It is not a true mineral, however, but a mixture of similar hydrated iron oxide minerals, mostly Goethite. Limonite forms mostly in or near...
