In addition, it has strong weather resistance, acid and alkali resistance, heat resistance up to 1200 degrees Celsius, suitable for coloring pigments for ceramics, glass, enamel, and other materials. The cobalt blue pigment has a bright color. The chemical composition of cobalt blue is CoO The Uses of Cobalt in the Field of Pigment 5. The Uses of Cobalt in the Field of P igment Cobalt Blue Pigment In vitamin B12 (alias cobalamin), which has special effects on hematopoiesis, the cobalt content is as high as 4.5%. In addition, cobalt is also used in artificial joint materials and dental fillings. Adding an appropriate amount of cobalt to penicillin can improve its curative effect.
#COBALT ELEMENT SKIN#
The radioactive isotope of cobalt can treat skin diseases and malignant tumors. 4. The Uses of Cobalt in the Medical IndustryĬobalt is also widely used in the medical field. Lithium cobalt oxide is a solid electrolyte with high energy density and high environmental safety.Ĭompared with Ni-Cd and Ni-Mn, the advantages of lithium batteries are wide voltage range, high energy density, and environmental protection. One of the cores of lithium-ion batteries is its positive electrode material, which uses lithium cobalt oxide (LiCoO2). The main use of cobalt is for lithium batteries. 3. The Uses of Cobalt in the Field of Battery MaterialĬurrently, nearly 40% of cobalt consumption is used for rechargeable battery materials, such as l ithium cobaltate for lithium-ion batteries and cobaltous oxide for nickel-metal hydride batteries. The use of cobalt-based alloys containing 20% -27% chromium in the structural materials of aviation turbine engines can achieve high oxidation resistance without using any protective coating. Therefore, the cobalt-based alloy is widely used in the aerospace and modern military fields. 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. Stellite hard alloys containing more than 50% cobalt will not lose their original hardness even if heated to 1000 ℃. This alloy is welded to the surface of the part and can increase the life of the part by 3-7 times. Tool steel containing a certain amount of cobalt can significantly improve its wear resistance and cutting performance. Cobalt combines other metal carbide grains in the alloy composition to make the alloy tougher and reduce the sensitivity to impact. 2. The Uses of Cobalt in the Field of Hard Alloy and Superalloy Cobalt steel loses only 2% -3.5% of its magnetism.īecause of its superior magnetic properties, cobalt is widely used in the manufacture of high-performance magnetic materials. Under the vibration environment, the general magnetic steel loses almost 1/3 of its magnetism. The magnetic steel containing 60% cobalt has a coercive force 2.5 times higher than that of ordinary magnetic steel.
Iron has a Curie point of 769 ° C, nickel of 358 ° C, and cobalt of 1150 ° C. The Uses of Cobalt in the Field of Magnetic MaterialĬobalt is one of the few metals that remain magnetic after a single magnetization. The temperature at which magnetism is lost by heat is called the Curie point.
