what is cosmoline used for


a rare, tin-white, brittle, nonmetallic chemical element, belonging to the same family of elements as sulfur and selenium and occurring naturally in mineral tellurite and tellurides: it is used as a glass tint, as an alloying material, and in thermoelectric converters: symbol, Te; at. It is a brittle, mildly toxic, rare, silver-white metalloid.Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens.It is occasionally found in native form as elemental crystals. Tamil meaning of Tellurium … The latter cation is formed by the reaction of tellurium with tungsten hexachloride:[30], Interchalcogen cations also exist, such as Te2Se2+6 (distorted cubic geometry) and Te2Se2+8. "dimethyl telluride (CHEBI:4613)". pp. Symbol Te. The city of Telluride, Colorado, was named in hope of a strike of gold telluride (which never materialized, though gold metal ore was found). Rubber can be vulcanized with tellurium instead of sulfur or selenium. [38] The square antiprismatic anion TeF2−8 is also attested. Tel′lurate, a salt of telluric acid.—adjs. Symbol: Te. This page provides all possible translations of the word tellurium in the Tamil language. Tamil Meaning of Tellurium. The Tamil people, also known as Tamilar (Tamil: தமிழர், romanized: Tamiḻar, pronounced in the singular or தமிழர்கள், Tamiḻarkaḷ, [tamiɻaɾxaɭ] in the plural) or simply Tamils (/ ˈ t æ m ɪ l s /), are a Dravidian ethno-linguistic group who trace their ancestry to the South Indian state of Tamil Nadu, Union territory of Puducherry or to Sri Lanka. Zhengtao Xu "Recent Developments in Binary Halogen–Chalcogen Compounds, Polyanions and Polycations" in Handbook of Chalcogen Chemistry: New Perspectives in Sulfur, Selenium and. Tellurium definition, a rare, lustrous, brittle, crystalline, silver-white element resembling sulfur in its properties, and usually occurring in nature combined with gold, silver, or other metals of high atomic weight: used in the manufacture of alloys and as a coloring agent in glass and ceramics. It would steadily build up your outcomes. A chemical element with symbol Te and atomic number 52, a silver grey metalloid. Tellurium is a chemical element.It has the chemical symbol Te and the atomic number 52. Thanks for using this online dictionary, we have been helping millions of people improve their use of the TAMIL language with its free online services. Pronounce word 150. Tellurium (Latin tellus meaning "earth") was discovered in 1782 by the Hungarian Franz-Joseph Müller von Reichenstein (Müller Ferenc) in Nagyszeben (now, Sibiu) Transylvania. With metallic element ending -ium. [53] The greatest purity metalorganics of both selenium and tellurium are used in these processes. Halotellurium cations are also attested, including TeI+3, found in TeI3AsF6. In the +4 oxidation state, halotellurate anions are known, such as TeCl2−6 and Te2Cl2−10. yellow tellurium . is known to be toxic. In contrast to selenium, tellurium does not usually replace sulfur in minerals because of the great difference in ion radii. Even though the metabolic pathways of tellurium are not known, it is generally assumed that they resemble those of the more extensively studied selenium because the final methylated metabolic products of the two elements are similar. Telluraethers (R–Te–R) are more stable, as are telluroxides. [30] The other halogens do not form halides with tellurium in the +6 oxidation state, but only tetrahalides (TeCl4, TeBr4 and TeI4) in the +4 state, and other lower halides (Te3Cl2, Te2Cl2, Te2Br2, Te2I and two forms of TeI). [27][25][26][28], The 1960s brought an increase in thermoelectric applications for tellurium (as bismuth telluride), and in free-machining steel alloys, which became the dominant use.[29].

The rubber produced in this way shows improved heat resistance. In 1798, it was named by Martin Heinrich Klaproth, who had earlier isolated it from the mineral calaverite. The +2 oxidation state is exhibited by the dihalides, TeCl2, TeBr2 and TeI2. [47][48][49] Replacing some of the cadmium in CdTe with zinc, producing (Cd,Zn)Te, produces a solid-state X-ray detector, providing an alternative to single-use film badges. After a thorough investigation that lasted three years and included more than fifty tests, Müller determined the specific gravity of the mineral and noted that when heated, the new metal gives off a white smoke with a radish-like odor; that it imparts a red color to sulfuric acid; and that when this solution is diluted with water, it has a black precipitate. Add a translation. In recent years, the tellurium price was driven up by increased demand and limited supply, reaching as high as US$100 per pound in 2006. It is a component of dusts from blast furnace refining of lead. • Tellurium (n.) A rare nonmetallic element, analogous to sulphur and selenium, occasionally found native as a substance of a silver-white metallic luster, but usually combined with metals, as with gold and silver in the mineral sylvanite, with mercury in Coloradoite, etc. Symbol Te. [36] Decomposition of ZnTe with hydrochloric acid yields hydrogen telluride (H2Te), a highly unstable analogue of the other chalcogen hydrides, H2O, H2S and H2Se: H2Te is unstable, whereas salts of its conjugate base [TeH]− are stable. Add thesaurus 100. This gemstone will help you change your negative thinking and start to make a positive cycle. [54][55], Tellurium, as tellurium suboxide, is used in the media layer of rewritable optical discs, including ReWritable Compact Discs (CD-RW), ReWritable Digital Video Discs (DVD-RW), and ReWritable Blu-ray Discs.[56][57]. National Renewable Energy Laboratory lab tests of tellurium demonstrated some of the greatest efficiencies for solar cell electric power generators. [19], In the gold rush of 1893, miners in Kalgoorlie discarded a pyritic material as they searched for pure gold, and it was used to fill in potholes and build sidewalks. [43] Tellurium also exhibits mixed-valence oxides, Te2O5 and Te4O9.[43]. Translate Tellurium.
