Calcium Carbonate Nanopowders and Nanoparticles

Displaying a dull gray-silver appearance in its elemental form, calcium is loed in such minerals as gypsum, plagioclases, dolomite, pyroxenes, and garnets. In addition to various industrial usages as an alloying agent, calcium also is also a biologically essential element found in bones, teeth, and shells.

Calcium - Element information, properties and uses

Calcium is what is known as an essential element, meaning that it is an element which is absolutely necessary for life processes. Which is what the old milk TV adverts were trying to tell us after all. Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation.

It''s Elemental - The Element Calcium

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 aluminum in hot, low-pressure containers. About 4.2% of the earth''s crust is composed of calcium.
