Cobalt was discovered by Swedish chemist George Brandt in 1735. Cobalt-60 is the longest-lived isotope of cobalt, with a half-life of 5.27 years. Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes! Chinese pottery from Tang (600-900 AD) and Ming dynasties (1350-1650 AD) also contained blue colours made from cobalt-containing minerals. * See Answer *Response times vary by subject and question complexity. Cobalt is also used to produce permanent magnets, such as the previously mentioned AlNiCo and samarium-cobalt magnets. Cobalt-60 has a half-life of 5.27 years and decays into nickel-60 through beta decay. The following uses for cobalt are gathered from a number of sources as well as from anecdotal comments. Hardmetals, in which cobalt is used as a binding material, consume roughly 12% of total cobalt. 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. Cobalt is a metal. Check out a sample Q&A here. Want to see the step-by-step answer? Cobalt is one of those often-neglected metals with a host of uses, interesting facts, and dynamic properties. Foods high in vitamin B-12 are the only source of cobalt used by the body. Unless you’re a geologist or an electrical engineer, you’d be forgiven for never giving this metal much thought. Cobalt-60 is used as the radiation source in Gamma Knife equipment that enables non-surgical treatment of brain tumours. These include cemented carbides and diamond tools that are used in cutting applications and mining tools. Therefore, exposures to gamma radiation from cobalt-60 result in an increased risk of cancer. Want to see this answer and more? See Answer. This is the case with pernicious anemia. 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. Cobalt is widely used in batteries and in electroplating. In the United States, it is most commonly used as part of superalloys. Cobalt is used in alloys for aircraft engine parts and in alloys with corrosion/wear resistant uses. Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. Cobalt is also used to make airbags in If you have a cobalt deficiency, this also means you have a vitamin B-12 deficiency. In cobalt-60 therapy, cobalt-60-generated gamma radiation is used to destroy tumors. Cobalt is an element used to make steel. Uses of cobalt. It is also used to prepare wear resistant and high strength alloys. Cobalt has a wide range of applications and is often used in many industrial processes. Uncontrolled disposal of 60 Co in scrap metal is responsible for the radioactivity found in several iron-based products. It is used chiefly for magnetic alloys, high-temperature alloys, and in the form of its salts for blue glass and ceramic pigments. Cobalt uses: Rechargeable batteries.
