Investigating the properties and Usage of Cobalt

This essay is about a study on characteristic and uses of cobalt. The aim of this research is to find out information about characteristic and uses of cobalt. Through library research regarding to its characteristic it is found that Cobalt is a silvery-gray metal that is commonly used as an alloy with Iron and is known for its high tendency to complexes. Cobalt is found in nature in minerals such as Cobaltite CoAsS and Erythrite (Co3(AsO4)2.8H2O), This metal is hard and has little chemical activity. Its reactivity is less than that of iron, and it reacts slowly with dilute acids, releasing Hydrogen Cobalt gives alloys the highest melting point, these alloys are used for armor, saws, and aircraft turbines.Cobalt is used in different areas of life such as industry and medicine.  Cobalt was used in ancient times as a bright pigment to color glass vases and as a dye in Egypt. Cobalt, like iron, is essential in our body’s metabolism. The Vitallium alloy is used in dentistry and bone surgery, etc. it is also used to make parts for rotary machines and gas turbines. Cobalt – 60, is used for radiography for cancer treatment. In agriculture cobalt ensures the health of plants and animals in the soil and provides the enzymes needed for their growth. It is also used to make permanent magnets. It is used in writing magnetic tapes and computer speakers and electric car motors.
