Calcium carbonate (CaCO 3) is one of the common compounds of calcium. It is heated to form quicklime (CaO) which is then added to water (H 2 O). This forms another material known as slaked lime (Ca(OH) 2) which is an inexpensive base material used throughout the chemical industry.lthough calcium is the fifth most abundant element in the earth's crust, it is never found free in nature since it easily forms compounds by reacting with oxygen and water. Metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).
