Cobalt
Cobalt is a silver-white metal with colored shades, which today is most often extracted from nickel ore by treatment with solutions of ammonia or sulfuric acid.
General characteristics
Cobalt metal is a heat-resistant wear-resistant alloy. He also resistant to demagnetization at high temperatures (1000 ° C and above) and loads. Distinguish following properties of cobalt:
- There are shades of blue, yellow and pink;
- Harder than iron — 5.5 points on Mohs scale;
- Viscous but fragile;
- Melting point 1494 °C;
- Boiling point 3185 °C, etc.
Metal is a rare metal due to low reserves in the earth’s crust. But demand for cobalt products is only increasing day by day.
Application area
In pure form, only 60Со radioactive isotope is used for manufacture of flaw detectors, which are used to detect cracks in metal products and for medical devices for ultrasound diagnostics. Besides cobalt is also used in production:
- Special alloys and steels;
- Processing tool: drills, cutters, etc.;
- Heat-resistant magnets;
- Chemically resistant materials;
- Li-ion batteries and accumulators;
- Thermoelectric generators with high efficiency and more.
Cobalt also used in agriculture and pharmaceuticals. It is added as a trace element for feed additives for livestock, bees and other animals, as well as for the manufacture of medicines for humans.
On sale you can find metal in form of ingots, sheets, powders and other convenient types of products.
