It is used in all of these industries in many ways. Cobalt is used in electroplating, a process in which a layer of material is applied to an object to give it a particular aesthetic or protective quality. Iron is more reactive and copper is less reactive. Therefore, the cobalt-based alloy is widely used in the aerospace and modern military fields. In addition, cobalt is also used in artificial joint materials and dental fillings. This alloy is welded to the surface of the part and can increase the life of the part by 3-7 times. I would be delighted to receive corrections as well as additional referenced uses.. alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses (jet engines and gas turbine engines) Cobalt is used in electroplating, a process in which a layer of material is applied to … It is used in magnets and magnetic recording media. Read More on This Topic cobalt processing: Cobalt-60 Currently, nearly 40% of cobalt consumption is used for rechargeable battery materials, such as lithium cobaltate for lithium-ion batteries and cobaltous oxide for nickel-metal hydride batteries. Cutting tools can be made with stellite alloys, which contain cobalt, chromium and tungsten. Sales agents were also oftentimes used by both parties. In a similar way, it is being used to make paint pigments. Cobalt is also p… Used as drying agents for paints and inks. Electroplating. ue to its good temperature resistance, corrosion resistance, and magnetic properties, cobalt is widely used in production and our life. Superalloys containing cobalt are used in the production of jet engines and gas turbine engines for energy generation. Cobalt is a silver-gray metal with element symbol Co, atomic number 27, a melting point of 1495 ℃, and a boiling point of 2870 ℃. Beneficial Uses of Cobalt-60 In the mid-1950s the increasing demand for sterile single-use medical devices led to a rapid expansion in the use of gamma irradiation to sterilize products as the technology provided a very effective means of ensuring sterility.

Application Of Tungsten And Tungsten Alloys, Advantages And Disadvantages Of Titanium Used in Automobile Industry, Properties & Applications of Molybdenum Copper Alloy. These properties have led to cobalt’s use in several core applications integral … In 1739, Georg Brandt discovered it while studying minerals that gave glass a deep blue color. Cobalt has been used by civilizations for centuries to create beautiful deep blue glass, ceramics, pottery and tiles. Stellite hard alloys containing more than 50% cobalt will not lose their original hardness even if heated to 1000 ℃. It is moderately reactive. These superalloys account for nearly half of the cobalt used eac… Cobalt-60 (60 Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. Alloys of cobalt make up half of global cobalt use each year. These magnets are used in hearing aids, microphones and compasses. The following uses for cobalt are gathered from a number of sources as well as from anecdotal comments. In cobalt-60 therapy, cobalt-60-generated gamma radiation is used to destroy tumors. Most cobalt used in the United States is imported. Adding an appropriate amount of cobalt to penicillin can improve its curative effect. Three of the main uses of cobalt are as a metal alloy, for electroplating and in batteries. The substance can also sterilize medical supplies. Lisa Rowan is a researcher and blog contributor. Although these naturally found alloys have interesting uses and properties, cobalt can be added to other elements like tungsten, nickel, and samarium to form superalloys. The temperature at which magnetism is lost by heat is called the Curie point. The basic chemical formula of iron-cobalt black is (Fe, Co) Fe2O4, which is mainly used for the coloring of ceramic green bodies. Cobalt salts have bee… 60Co isotope used as radioactive tracer for the production of gamma rays. COBALT MAY NOT BE RARE, BUT IT IS VALUABLE. Cobalt deficiency in animals, especially ruminants, can cause diseases such as decreased digestive capacity and anemia, so trace cobalt is widely added to animal feed. Some alloys go into making jet engines and gas turbine engines. Therefore, the cobalt-based alloy is widely used in the aerospace and modern military fields. It is also is specifically made for use in gamma irradiation plants – it is not a waste product of nuclear power plants. Despite the many uses for cobalt metal, cobalt's primary applications are in the chemical sector, which accounts for about half of the total global demand. Tool steel containing a certain amount of cobalt can significantly improve its wear resistance and cutting performance. It is alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses. Cobalt salts are used to produce vivid shades of blue in porcelain, glass, pottery and tiles. Due to its good temperature resistance, corrosion resistance, and magnetic properties, cobalt is widely used in production and our life. Compared with Ni-Cd and Ni-Mn, the advantages of lithium batteries are wide voltage range, high energy density, and environmental protection. It is also used as catalysts for the petroleum and chemical industries. Cobalt improves the performance of rechargeable batteries and plays an important role in hybrid electric vehicles. Another alloy, called Alnico, consists of of aluminum, nickel and cobalt and is strongly magnetic. Due to its appearance, hardness and resistance to corrosion, cobalt is often used in electroplating. These are called biochemical reaction activators. Uses of Cobalt Cobalt is used in alloys for aircraft engine parts and in alloys with corrosion/wear resistant uses. In addition to these traditional uses, cobalt is used in a number of industrial applications. Cobalt is widely used in batteries and in electroplating. Cobalt is widely used in batteries and in electroplating. As previously mentioned, cobalt is usually found as an alloy within the earth. When the producers controlled the cobalt market, the majority of its sales occurred as direct transactions between the producers and the consumers. In medicine, it is used to treat cancer and to sterilize medical equipment. Despite being relatively common, it's … Lithium cobalt oxide is a solid electrolyte with high energy density and high environmental safety. Cobalt is a hard gray metal element. Cobalt is also a bio-essential element and is found in the centre of vitamin B12. When the temperature is above 1038 ℃, the superiority of the cobalt-based alloy is revealed, and it is particularly suitable for making high-efficiency high-temperature engines and steam turbines. If you want to know more about the cobalt or other refractory metals, you can visit Advanced Refractory Metals (ARM) for more information. When water is present, the test paper goes from blue to pink. Cobalt is used in alloys for aircraft engine parts and in alloys with corrosion/wear resistant uses. Under the vibration environment, the general magnetic steel loses almost 1/3 of its magnetism. The element has been used for hundreds of years, but was named in 1735 by a chemist named Brandt.
