Plansee Group
The Plansee Group (named after Lake Plansee; company name: ''Plansee Holding AG)'' is an Austrian company based in Reutte that specialises in the powder metallurgical production of materials (molybdenum and tungsten) and in processing them into tools and moulded parts. The Plansee Group is a private company and is considered a global market leader.''Die Weltmeister des Exports'', Kurier, (Österreich) vom 13. September 2018, Seite I2, I4, I6. History Paul Schwarzkopf (born 13 April 1886), an industrial entrepreneur and pioneer in the powder metallurgy field, founded Metallwerk Plansee GmbH in 1921. Schwarzkopf, who was searching for a suitable production site close to a hydropower station at the time by placing a newspaper advertisement, ultimately decided in favour of Reutte. Between 1929 and 1931, the company started to produce carbides and hard materials using new and specially developed approaches. In 1938, Schwarzkopf was expropriated following the annexation of ...

Austria-Forum
Austria-Forum is a freely accessible online collection of reference works in both German and English about Austria-related topics. Background The predecessor of Austria-Forum, the AEIOU project was launched in 1996 by the Austrian Federal Ministry for Science and Research as part of Austria's millennial celebrations. The first mention of the name ''Ostarrîchi'', or Austria was in the year 996. The content was based on the German-language ''Österreich-Lexikon'', first published in a printed version in 1995. Additional material was acquired, including more images and also audio and video files, and ''AEIOU'' soon grew into a multimedia information system. The title ''AEIOU''—the "Annotatable Electronic Interactive Oesterreich Universal Information System"—is an allusion to the old Habsburg motto, A.E.I.O.U. Suggestions for the improvements to articles can be made by reader; however, the ''aeiou Encyclopedia'' was not a wiki. See also * List of online encyclopedias This ...

Rhenium
Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust. Rhenium has the third-highest melting point and highest boiling point of any stable element at 5869 K. Rhenium resembles manganese and technetium chemically and is mainly obtained as a by-product of the extraction and refinement of molybdenum and copper ores. Rhenium shows in its compounds a wide variety of oxidation states ranging from −1 to +7. Discovered by Walter Noddack, Ida Tacke and Otto Berg in 1925, rhenium was the last stable element to be discovered. It was named after the river Rhine in Europe, from which the earliest samples had been obtained and worked commercially. Nickel-based superalloys of rhenium are used in combustion chambers, turbine blades, and exhaust nozzl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santiago
Santiago (, ; ), also known as Santiago de Chile, is the capital and largest city of Chile as well as one of the largest cities in the Americas. It is the center of Chile's most densely populated region, the Santiago Metropolitan Region, whose total population is 8 million which is nearly 40% of the country's population, of which more than 6 million live in the city's continuous urban area. The city is entirely in the country's central valley. Most of the city lies between above mean sea level. Founded in 1541 by the Spanish conquistador Pedro de Valdivia, Santiago has been the capital city of Chile since colonial times. The city has a downtown core of 19th-century neoclassical architecture and winding side-streets, dotted by art deco, neo-gothic, and other styles. Santiago's cityscape is shaped by several stand-alone hills and the fast-flowing Mapocho River, lined by parks such as Parque Forestal and Balmaceda Park. The Andes Mountains can be seen from most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tungsten Carbide
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, cutting tools, chisels, abrasives, armor-piercing shells and jewelry. Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa, and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-) in hardness and can be polished and finished only with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels and compounds. Naming Historically referred to as Wolfram, ''Wolf Rahm'', wolframite ore was then later carburized and cemented with a binder creating a composite now called "tungsten carbide". Tungsten is Swedish for "heavy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonium Paratungstate
Ammonium paratungstate (or APT) is a white crystalline salt with the chemical formula (NH4)10(H2W12O42)·4H2O. It is described as "the most important raw material for all other tungsten products." Production From tungsten ores Tungsten ores, which are typically oxides, are digested in base to give solutions of tungstate together with many contaminating species. This crude extract is acidified and treated with sulfide Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions. Solutions of sulfide salts are corrosive. ''Sulfide'' also refers to chemical compounds lar ... to separate molybdenum trisulfide. Upon further acidification APT eventually crystallizes. Laboratory methods If a calcined WO3 is used, refluxing the ammonia solution is advisable to accelerate its dissolution. Conversion to tungsten metal Heating ammonium paratungstate to its decomposition temperature of 600& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heavy Metals
upright=1.2, Crystals of lead.html" ;"title="osmium, a heavy metal nearly twice as dense as lead">osmium, a heavy metal nearly twice as dense as lead Heavy metals are generally defined as metals with relatively high density, densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical property, chemical behaviour. More specific definitions have been published, but none of these have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them. Despite this lack of agreement, the term (plural or singular) is widely used in science. A density of more than 5 g/cm3 is som ...
