![]() ![]() Cobalt is graphically represented by a ‘kobold’ or goblin (considered troublesome by the medieval German miners) with some Chinese porcelain in the background, referring to its use as a pottery glaze in ancient China.Ĭobalt Mineral (Cobaltite) Interesting Facts Small doses of cobalt are also given to some animals to prevent mineral deficiencies in them. ![]() It is found in trace amounts in humans and is an essential component of vitamin B12. In large quantities, cobalt can be carcinogenic in humans and some animals. Ĭobalt poisoning can take place when you accidentally ingest, breathe, or have it in contact with the skin in large amounts. Stellite super-alloys, composed of chromium, cobalt, and tungsten, are used for making high temperature and high wear resistant cutting tools.Radioactive 60Co is used for treating cancer, and in food irradiation for controlling pathogens and extending shelf life.Cobalt salts are used to impart intense blue colors in glass, porcelain, pottery, enamels, and paint.It is commonly used as a cathode material in lithium ion batteries.Cobalt is occasionally used in electroplating owing to its hardness and attractive appearance.Cobalt is alloyed for use in gas turbine generators and jet turbines because of its high-temperature strength and resistance to corrosion.State of matter at room temperature (solid/liquid/gas)Ĭobalt Electron Configuration ( Bohr Model) What is Cobalt Used for However, his fellow Swedish chemist Torbern Bergman conducted further studies and confirmed Georg Brandt’s discovery in 1780. His discovery was controversial, as other chemists disputed his findings for many years. He described its properties and published the results in 1739. Finally, he succeeded in proving that the blue ore contained a new metal. Īside from its ancient origins, its discovery in the recent times dates back to the 1730s when Georg Brandt was interested in a blue ore from some of the local mines. In China, cobalt blue was used for making pottery glazes. The tomb of Tutankhamen, the ancient Egyptian Pharaoh who ruled during 1361-1352 BC, had a deep blue glass object that was made of cobalt. Who discovered it: The element was found by the Swedish chemist and mineralogist Georg Brandt. Origin of its Name: The name is derived from ‘kobald’, German for “goblin” and from ‘cobalos’, a Greek word meaning “mine”.
