1/7/2024 0 Comments Cobalt metalCobalt has a property to maintain its magnetism even at higher temperatures.So it is used as a coloring agent in manufacturing various other materials. When cobalt combines with other elements, it can give other different colors.Cobalt is used in manufacturing inks, glass, paints that require a blue colouring agent.Cobalt is used mainly as an alloying element in manufacturing of superalloys which possess anticorrosive properties as well as they are also stable at higher temperature.Hence it is classified as a transition metal on the periodic table. If cobalt is kept open in the air, it slowly reacts with the oxygen of the air and forms cobalt oxide.But it is always found as a compound with other elements. As cobalt is fairly reactive, it is not found in a free state in nature.Chemical properties of CobaltĬhemical properties of cobalt are mentioned below. The atomic mass of cobalt is 58.933 u and its density is 8.9 g/cm 3.There are various synthetic isotopes of cobalt, but the most abundant naturally occurring stable isotope is the 59Co.The melting point of cobalt is 1495 ☌ and its boiling point is 2927 ☌.Cobalt is a transition metal having bluish lustrous grey metallic surface.Physical properties of cobalt are mentioned below. The physical and chemical properties of cobalt element are mentioned below. Cobalt is obtained as a byproduct while mining other metals (especially copper and nickel).Around 30% of cobalt produced nowadays is used in ceramics industries as well as paints industries.Cobalt is also present in the human body, but its excess amount can be dangerous.Africa is the leading producer of cobalt in the world.Also cobalt can maintain the magnetism at high temperatures. Cobalt is one of the few metals that are naturally magnetic.The abundance of cobalt in earth’s crust is around 25 ppm (parts per million) by weight.Cobalt is the name derived from the German word “kobald” (meaning “goblin”).Interesting facts about cobalt element are mentioned below. In order to have the complete d-orbitals, there must be 10 electrons in it.īut in the ground state electronic configuration of cobalt, you can see that it has only 7 electrons in d-orbitals.Īnd hence, as Cobalt has incomplete d-orbitals, it is considered as a transition metal. HCP (Hexagonal close packing) Melting point 1768 K or 1495 ☌ or 2723 ☏ Boiling point 3200 K or 2927 ☌ or 5301 ☏ Density 8.9 g/cm 3 Main isotope 59Co Who discovered Cobalt and when? Georg Brandt in 1735 CAS number īecause, there are only seven electrons in the d-orbitals.
