The Many Uses of the Element Cobalt
There are many elements in the world and one of them is cobalt. It is a silvery blue metal with a blue coat. It is element number twenty-seven on the table which means that it has twenty-seven protons and electrons. One mole or its atomic weight is 58.9 grams. It has a relatively high melting and boiling point, the melting point being 1,495 degrees Celsius or 2,723 Fahrenheit and the boiling point being 2,927 degrees Celsius or 5,301 Fahrenheit. The top three countries that mine this element are the District Republic of the Congo, Cuba, and Australia in that order. Cobalt has had and still has many uses in the world today.

Cobalt is used in magnets and electronics in quite a few ways. One use for cobalt is in magnetic alloys that are meant to keep a magnetic field for a certain period of time. These fields are used in motors and generators (Newton). Cobalt is used in these fields for many reasons. The main reason though is that cobalt has a high Curie temperature. A Curie temperature is basically how hot a metal can be heated while maintaining its magnetism. Cobalt’s Curie temp is 1,121 degrees Celsius. Cobalt also has a high magnetic power and tesla (magnetic density) (Cobalt Facts). Cobalt is also used in various electronics. Cobalt is used because it has the power to carry and direct currents like other metals. Cobalt is used in circuits and semi-conductors because of this. Cobalt is also used in batteries. Cobalt is used as a powder in batteries to raise the power while stabilizing the battery at the same time. One of the main visual uses of cobalt though, is in chemistry.
Cobalt has many uses in the aspect of Chemistry. One of the main uses is a catalyst in petroleum. Specifically, CoMoO4 is used to help change petroleum into gas (Newton). This chemical removes the sulfur in the oil to make it a useable fuel source. Also cobalt is used as a catalyst to speed up the resin process when making plastics (Cobalt Facts). Cobalt is also used to produce bright blue colors in paints (Cobalt Periodic). They are also in many other chemical dyes and paints and they can help determine how quickly these paints dry which can be very important to artists (Cobalt Facts). They are also used in dyes for glass, glazes, cosmetics, inks, and pottery (Newton). Here is a chart on chemical combinations used to make colored paints. Cobalt is in many chemicals but can be an important part of the environment and agriculture as well.
Cobalt is a very important part of the environment. Part of this comes from the fact that the element has the vitamin B12. Cobalt is needed for some animals because of this but the animals only need a little of this vitamin. Animals...
