calcium | Definition, Properties, & Compounds | Britannica
Occurrence, properties, and uses Calcium does not occur naturally in the free state, but compounds of the element are widely distributed. One calcium compound, lime (calcium oxide, CaO) was extensively used by the ancients.The silvery, rather soft, lightweight metal itself was first isolated (1808) by Sir Humphry Davy after distilling mercury from an amalgam formed by electrolyzing a mixture

Baerlocher: Metal Soaps
Metal soaps are derived from long-chain fatty acids and a metal oxide compound. The fatty acids, in turn, are derived from a triglyceride (natural fats and vegetable oils, i.e. renewable feedstocks). Metal soaps – commonly known as metallic stearates – can be produced using various synthesis methods, e.g. precipitation and melting processes.
