Health Impacts of CobaltĬobalt is an essential mineral that the body needs for good health. Batteriesīatteries are classified according to their voltage.Ī battery with a voltage of 1.5 volts is a AA battery.Ī battery with a voltage of 3.6 volts is a lithium ion battery. Some common alloys that contain cobalt are:Ĭobalt is also used in the production of magnets and in the refining of oil. Applications of CobaltĬobalt is mostly used in the production of alloys. The metallic zinc can then be oxidized to zinc oxide and the cobalt can be extracted from the zinc oxide with sulfuric acid. Extraction of Cobaltfrom Zinc OresĬobalt can be extracted from zinc ores by converting the zinc to zinc oxide and then reducing the zinc oxide to metallic zinc with carbon. The gamma ray is then used to irradiate food, medical supplies, or other objects that need to be sterilized. When the unstable cobalt-60 decays, it releases a gamma ray. The nickel-59 is a stable isotope, while the cobalt-60 is an unstable isotope that decays radioactively. The isotope cobalt-60 is most commonly produced commercially by bombarding nickel-59 with neutrons in a nuclear reactor. Cobalt is also used in the production of magnets, batteries, and surgical implants. It is used to make alloys with other metals, such as nickel and iron, to create strong, durable materials. Cobalt is a hard, brittle metal that is resistant to corrosion. It has a silver-white color and a metallic luster. Occurrence of CobaltĬobalt is a transition metal that is found in Group 10 of the periodic table. It is a magnetic metal and has a very high melting point. It is found in the Earth’s crust at a concentration of about 0.003%. Characteristics of CobaltĬobalt is a hard, brittle, silver-grey metal. Cobalt is used in the production of some types of catalysts because it helps to stabilize the catalyst and improve its performance. Catalysts are substances that speed up chemical reactions. The addition of cobalt makes the alloy stronger and more resistant to corrosion.Ĭobalt is also used in the production of catalysts. Magnets are made of alloys that contain iron, nickel, and cobalt. Stainless steel is a combination of iron, chromium, and nickel, and cobalt is added to the mix to improve the alloy’s resistance to corrosion.Ĭobalt is also used to make magnets. The most common use of cobalt is in the production of stainless steel. The metal is produced by reducing the oxide with carbon.Ĭobalt has several important industrial applications, including in the production of corrosion-resistant alloys, magnets, and catalysts. It is a silver-white, lustrous, hard metal with a high melting point.Ĭobalt is found naturally as the free element and in combination with nickel and iron in minerals. Cobalt is a chemical element with symbol Co and atomic number 27.
