An Introduction to Calcium Metal - MMTA

13.04.2016· Calcium is, however, a metal in its pure form, though rarely seen in this state due to its instability. In air, calcium decomposes rapidly into calcium hydroxide and calcium carbonate. Calcium carbonate is the chalky substance we associate with calcium, with the white cliffs of Dover (see right) being composed of this compound.

It''s Elemental - The Element Calcium

Although 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).

Calcium Metal - an overview | ScienceDirect …

The production process of calcium metal by the metallothermic reduction process (see Equation 2.9.43) is shown in Figure 2.9.43. The raw material CaCO 3 is calcined to produce CaO. Low magnesia content (MgO) is preferred for the reduction feed materials because magnesia is preferentially reduced in this process, thus lowering the reaction efficiency for calcium metal.
