An Introduction to Calcium Metal - MMTA

13.04.2016· He was correct, and metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO). Today, metallic calcium is obtained by displacing calcium atoms in lime with atoms of aluminium in hot, low-pressure containers. Due to its high reactivity with common materials, there is very little demand for metallic calcium.
