11 Jan uses of cobalt
Cobalt has been used to colour pottery and glass for at least 2600 years evidenced by cobalt-containing glazes having been found in Ancient Egyptian tombs. Cobalt is used mainly in production of chemicals (58 percent), super alloys for gas turbine blades and jet aircraft engines, special steel, carbides, diamond tools and magnets. Cobalt-60 is a beta-emitting radioactive isotope of cobalt-59. Want to see this answer and more? Radioactive 60 Co is used in the treatment of cancer. Uncontrolled disposal of 60 Co in scrap metal is responsible for the radioactivity found in several iron-based products. Cobalt salts are used to impart blue and green colors in glass and ceramics. A solution of the chloride is used as a sympathetic ink. Importance and uses of cobalt(II) sulphate (CoSO4.7H2O) check_circle Expert Answer. Cobalt-60 has a half-life of 5.27 years and decays into nickel-60 through beta decay. test, or Thin-layer Rapid Use Epicutaneous Test. Cobalt uses: Rechargeable batteries. All ionizing radiation, including that of cobalt-60, is known to cause cancer. Chinese pottery from Tang (600-900 AD) and Ming dynasties (1350-1650 AD) also contained blue colours made from cobalt-containing minerals. In cobalt-60 therapy, cobalt-60-generated gamma radiation is used to destroy tumors. Cobalt is a hard, lustrous, grey metal with a high melting point (1493°C). Symptoms can include numbness, fatigue and tingling in your hand and feet. Cobalt is a metal. Cobalt is used for a wide range of applications including: The manufacture of super-alloys, the primary application of cobalt produced today. Uses of cobalt. This is a gamma sterilization process which uses Cobalt 60 radiation to kill microorganisms on a variety of different products. Some common forms of cobalt include cobalt-60 and cobalt chloride. Cobalt is widely used in batteries and in electroplating. Cobalt-60 is the longest-lived isotope of cobalt, with a half-life of 5.27 years. Want to see the step-by-step answer? balt (kÅâ²bôltâ²) n. Symbol Co A hard, brittle metallic element, found associated with nickel, silver, lead, copper, and iron ores and resembling nickel and iron in appearance. To counteract this, cobalt must be used. In addition, increasing the proportion of nickel leaves the battery less thermally stable, a property that may be counterbalanced by manganese, a mineral that has no exothermic tendency. Glossary. Cobalt. Median response time is 34 minutes and â¦ Cobalt salts have been used for centuries to produce brilliant and permanent blue colors in porcelain, glass, pottery, tiles, and enamels. Cobalt is one of the key ingredients, along with other metals like lithium, nickel and manganese, inside these fast-charging, long-lasting batteries that power our digital lives. Cobalt is also used as a blue coloring agent in paints, inks, glass, ceramics, and even cosmetics. Unlike lithium, much of cobalt is found in one place, the Democratic Republic of the Congo, or DRC â 59 per cent of the world's supply is sourced from that country. Cobalt is also used to make alloys for jet engines and gas turbines, magnetic steels and some types of stainless steels. Cobalt is used to build lithium-ion batteries found in mobile technology. Transition metals = Used in Alloys Pottery Cobalt is used in both glazes and the manufacture of pottery, ceramics, and even the tiles on your roof. Trace Element Your body actually needs cobalt to survive. Check out a sample Q&A here. Cobalt is an element used to make steel. Unless youâre a geologist or an electrical engineer, youâd be forgiven for never giving this metal much thought. Anemia is a main cause of a cobalt deficiency. These include cemented carbides and diamond tools that are used in cutting applications and mining tools. Cobalt-60 is a widely used radioactive material. Itâs best to take cobalt in vitamin B-12. The following uses for cobalt are gathered from a number of sources as well as from anecdotal comments. Cobalt-60 is used as the radiation source in Gamma Knife equipment that enables non-surgical treatment of brain tumours. In the United States, it is most commonly used as part of superalloys. The famed "cobalt blue" is actually the result of the compound cobalt aluminate. See Answer. Cobalt is one of those often-neglected metals with a host of uses, interesting facts, and dynamic properties. It is also used to prepare wear resistant and high strength alloys. Cobalt-60 is used in the inspection of materials Cobalt assets. This is the case with pernicious anemia. I would be delighted to receive corrections as well as additional referenced uses. It is also is specifically made for use in gamma irradiation plants â it is not a waste product of nuclear power plants. Magnets account for 7% of cobalt metal demand and are used â¦ * See Answer *Response times vary by subject and question complexity. In industry Cobalt-60 is used for industrial radiography, a form of non-destructive testing; in well logging, particularly in the oil exploration industry; and in the printing industry to monitor the Ëow of inks and thickness of paper. Cobalt was discovered by Swedish chemist George Brandt in 1735. The rechargeable lithium ion batteries in your smartphone, tablet and electric vehicle run, at least in part, on cobalt. It is used to produce many types of alloys including stainless steel. It is used chiefly for magnetic alloys, high-temperature alloys, and in the form of its salts for blue glass and ceramic pigments. It is the principal ingredient in Sevre's and Thenard's blue. Around 1983, construction was finished of 1700 apartments in Taiwan which were built with steel contaminated with cobalt-60. Cobalt looks set to become one of the most important commodities in delivering the electric vehicle revolution â thanks to rising demand for the metal in the batteries that power them. By integrating cobalt into a Significance and Uses. If you have a cobalt deficiency, this also means you have a vitamin B-12 deficiency. Foods high in vitamin B-12 are the only source of cobalt used by the body. Properties, sources and uses of the element cobalt. Cobalt-60, a radioactive isotope of cobalt, is an important source of gamma rays and is used to treat some forms of cancer and as a medical tracer. 60 Co isotope used as radioactive tracer for the production of gamma rays. How was it discovered? Cobalt in other chemical combinations can also make a variety of other colors. The T.R.U.E. Cobalt is also used to produce permanent magnets, such as the previously mentioned AlNiCo and samarium-cobalt magnets. Cobalt-60 is also used in blast furnaces to determine times and to quantify income to measure the furnace performance.
