One of the three metals that exhibit ferromagnetism at normal temperature is cobalt. It can be used in situations where magnetic qualities are required at high temperatures since it is ferromagnetic up to 1,121 ☌ (2,050 ☏), which is the highest known Curie point of any metal or alloy. There are two known allotropes: the face-centered cubic, which is stable at high temperatures, and the hexagonal close-packed structure, which is stable below 417 ☌ (783 ☏). Cobalt-60, which has a half-life of 5.3 years and is frequently employed in medicinal applications, is the most common.Ĭobalt, in general, is a silver-white with a slightly blue hue, polished metal. At temperatures below 417 ☌ (783 ☏), it exhibits a hexagonal closed pack crystal structure and contains 12 radioactive isotopes. Boiling Point is recorded at 5612☏ or 2870☌. The Classification includes Crystallized Transition Metal Hexagonal close-packed structure. Its sign is “Co.” Its Atomic Weight is 27. Cobalt’s main characteristics are listed below: It has excellent conduction qualities and a high strength. It has a high melting point and endures well in hot conditions. The ferromagnetic metal cobalt is hard but fragile.

It is a member of the periodic table’s first-row transition series and cannot be found naturally in its purest form rather, it can only be found in combinations with other elements. Cobalt is unaffected by water and stable in air, although weak acids progressively corrode it. Chemically, the element is active, creating several compounds.
Its physical characteristics are comparable to those of nickel and iron. It belongs to the periodic table’s group VIII. Cobalt is a brittle, silver-white, hard, ferromagnetic, and glossy element. In nature, cobalt (Co) is a rare metal element that makes up 0.001% of the crust of the planet. In many uses, it is typically mixed with iron to create various alloys. Cobalt is an ore that, when properly mined and polished, yields a beautiful, bluish-white metal.
