History:

 

The name of the metal is derived from the German word Kobold meaning «goblin». Compounds of cobalt were known and were applied from the remotest antiquity. The discovered Egyptian glass jug that is painted using cobalt salts and blue vitreous bricks containing cobalt are dated to the XV century BC. In ancient Assyria, and also in Babylon cobalt was used to create a lazurite glaze for stoneware.

 

Use:

 

Cobalt is an important alloying element improving properties of alloys, including special steels. The metal is used in manufacturing cutting tools and equipment parts coatings. Cobalt is one of the few metals that can retain its magnetic properties if magnetized once; it is used in manufacturing of cores of electric motors, transformers and other electrical devices. In chemical industry cobalt compounds are used as catalysts in various processes. Cobalt saltsare added to paints and varnishes to accelerate their drying. Lithium cobaltate is used for manufacturing of lithium electrodes in batteries. The metal is used in manufacturing of aircraft engines andhigh efficiency thermoelectric generators. Cobalt compounds are used in manufacturing of blue and light blue decorative glass. Radioactive cobalt is used in medicine and research studies as a source of gamma rays.
