Cobalt is a blue transitional metal that occupies the middle of the periodic table. It is a ferromagnetic metal. For centuries, The ancients have used cobalt to give a blue-color to glass and ceramics. This element represents 0.001% of the Earth’s crust. Cobalt is present in small quantities in the earth and meteorites as well as the sun and stars. The metal is also an essential element for human health and Participates in vitamin B12 Production.
Facts about cobalt :
- Atomic number (number of protons in the nucleus): 27, while its atomic symbol (on the periodic table of elements): Co
- Atomic weight (average mass of the atom): 58.933195
- Density: 8.86 g per cubic centimeter
- at room temperature: solid
- Melting point: 2723°F (1495°C), while its Boiling point: 5301 F (2927°C)
- The number of isotopes (atoms of the same element with a different number of neutrons): 8; but only 1 is stable
- The pure form of cobalt is fragile. It is similar to iron and nickel and can be magnetized like iron.
- Most common isotopes: Co-59 (100% natural abundance)
- slowly dissolves in diluted mineral acids.
The uses of cobalt:
- The impure form of cobalt has popular use as a dye.
- Cobalt and aluminum alloys engage in manufacturing high-strength magnets and high-tech turbines.
- Aman-made isotope co 60 engages in the treatment of cancer. This radioactive isotope release a gamma-ray that can target tumors, especially brain tumors that require careful treatment.
cobalt has other uses in :
- Electrical lamination and in battery making.
- The ceramic, glass and ceramic industries to compress blue and green colors into it.
- The manufacture of paints as dried material for paint and varnish.
- With aluminum, nickel, and iron to make magnets of radios, televisions and many other electronic means.
- Piercing and cutting tools.
- Gas turbines and jet engines.
The average cobalt price ranges from $7,456-7,600) per tonne. Price may vary according to the grade of cobalt. Experts expect that prices will increase due to the corona crisis.
