Transcript of Super Awesome Cobalt Prezi

Chemical Properties Physical Properties Extraction Process Lithium cobalt oxide is used in lithium batteries. Cobalt can also be used to make paints and to stain glass blue. It can be found in most superalloys, which are used in jet engines and gas turbines. Common Uses Cobalt can be found in China, Russia, Australia, and the Democratic Republic of Congo. It is found as an ore and is often obtained as a byproduct of mining copper and nickel.

58 Cobalt is in the ninth family and belongs to the fourth period. It is classified as a transition metal. Cobalt is most commonly found as a solid. Discovered by Swedish chemist George Brandt in 1735
Discovered in Sweden
George Brandt thought that it was not bismuth that turned glass blue, which was the common belief of the time, but an undiscovered element. Brandt was correct in his hypothesis and came to call that element cobalt. This is cobalt on
the periodic table This is an atom
of cobalt. Cobalt is extracted by using heat from a blast furnace and a metal reducing agent, such as carbon, to change the ore's oxidized state. The carbon removes the ore's oxygen and leaves the metal cobalt. The cobalt is taken out to obtain 99.9 percent pure cobalt.
