Allergic contact dermatitis is an inflammation of the skin that can occur when people come into contact with a substance to which they are allergic. Superalloys, which are used to make parts for gas turbine engines, are another major use for cobalt. The T.R.U.E. The latter contains cobalt in both +2 and +3 oxidation states and constitutes up to 40 percent of the commercial cobalt oxide used in the manufacture of ceramics, glass, and enamel and in the preparation of catalysts and cobalt metal powder. * See Answer *Response times vary by subject and question complexity. These include cemented carbides and diamond tools that are used in cutting applications and mining tools. One of cobalt’s main applications right now is in rechargeable batteries of all kinds. Cobalt blue is a vivid color used in artwork. Cobalt-60 is used in the inspection of materials These substances, which include foods, plant pollens and metals, are called allergens. Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. Properties, sources and uses of the element cobalt. Cobalt is an element used to make steel. These super-alloys are, in turn, used in turbine blades for jet aircraft engines and gas turbines; medical orthopedic implants like hip and knee replacements; and permanent magnets. Cobalt is also used as a blue coloring agent in paints, inks, glass, ceramics, and even cosmetics. Cobalt is also used to make airbags in Cobalt is used in many alloys (superalloys for parts in gas turbine aircrafr engines, corrosion resistant alloys, high-speed steels, cemented carbides), in magents and magnetic recording media, as catalysts for the petroleum and chemical industries, as drying agents for paints and inks. By integrating cobalt into a Cobalt salts have been used for centuries to produce brilliant and permanent blue colors in porcelain, glass, pottery, tiles, and enamels. It’s best to take cobalt in vitamin B-12. Much of it comes from Congo, where men, women, and children endure dangerous and unhealthy conditions to … In cobalt-60 therapy, cobalt-60-generated gamma radiation is used to destroy tumors. Cobalt in other chemical combinations can also make a variety of other colors. Importance and uses of cobalt(II) sulphate (CoSO4.7H2O) check_circle Expert Answer. Cobalt. All ionizing radiation, including that of cobalt-60, is known to cause cancer. On a global basis, the leading use of cobalt is in rechargeable battery electrodes. 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. 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 ˚ow of inks and thickness of paper. It is the principal ingredient in Sevre's and Thenard's blue. The rechargeable lithium ion batteries in your smartphone, tablet and electric vehicle run, at least in part, on cobalt. Cobalt-60 is a beta-emitting radioactive isotope of cobalt-59. Cobalt is a mineral that doesn’t get enough attention despite its ability to stimulate systemic antioxidant and anti-inflammatory processes, according to two American researchers. 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. Currently, the traditional areas of consumption and application of cobalt are mainly battery materials, super heat-resistant alloys, tool steels, hard alloys, magnetic materials; cobalt in the form of compounds is mainly used as catalysts, desiccants, reagents, pigments and dyes. Cobalt assets. It is also used to prepare wear resistant and high strength alloys. 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. Cobalt is a silvery gray metal that has diverse uses based on certain key properties, including ferromagnetism, hardness and wear-resistance when alloyed with other metals, low thermal and electrical conductivity, high melting point, multiple valences, and production of intense blue colors when combined with silica. Foods high in vitamin B-12 are the only source of cobalt used by the body. Cobalt is used to build lithium-ion batteries found in mobile technology. On the periodic table, cobalt can be found among the d-block elements, transition metals . Cobalt was discovered by Swedish chemist George Brandt in 1735. Unlike lithium, much of cobalt is found in one place, the Democratic Republic of the Congo, or DRC – 59 per cent of the world's supply is sourced from that country.
