Silicones
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or elastomer, rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone Caulking, caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and Cross-link, crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elkem Thamshavn
Elkem Thamshavn is a smelting plant owned by Elkem located at Thamshavn just north of Orkanger in Orkland Municipality in Trøndelag county, Norway. The plant produces silicon and microsilica and was started in 1931. History Copper and Sulfur have been excavated in the Løkken Mines since 1654 that had to be freighted down to Orkanger and onwards to Europe by ship. In 1867, Wilhelm Thams built a sawmill at Thamshavn, and the place took the surname of his family. His grandson Christian Thams, together with Christian Salvesen, bought the mines at Løkken Verk in 1904 and constructed a railway, Thamshavnbanen, from the mine and down the to the port at Thamshavn. In 1931 Orkla Metall was opened, officially owned by the subsidiary Chr. Salvesen & Chr. Thams's Communications Aktieselskab that also owned the railway and the hydro electric power plant. The original function of the plant was to smelt the pyrites from the mine into sulphur and copper matte. This lasted until 1962 when ...

Anthracite
Anthracite, also known as hard coal, and black coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 97%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. The Coal Region of northeastern Pen ...

Calcined
Calcination refers to thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone (calcium carbonate) through combustion to yield calcium oxide (quicklime). This calcination reaction is CaCO3(s) → CaO(s) + CO2(g). Calcium oxide is a crucial ingredient in modern cement, and is also used as a chemical flux in smelting. Industrial calcination generally emits carbon dioxide (), making it a major contributor to climate change. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550–1150 °C, or 1000–2100 °F) within a controlled a ...
