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

Calcite - Wikipedia

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at

Water Treatment Storage and Blowdown for Steam Boilers | Spirax …

Total hardness is not to be classified as a type of hardness, but as the sum of concentrations of calcium and magnesium ions present when these are both expressed as CaC03. If the water is alkaline, a proportion of this hardness, equal in magnitude to the total alkalinity and also expressed as CaC03, is considered as alkaline hardness, and the remainder as non-alkaline hardness (See Figure 3.9.5).
