1.(Minerals) a white mineral often tinted by impurities, found in sedimentary rocks and veins. It is used in the manufacture of cement and as a building stone (marble). Composition: calcium magnesium carbonate. Formula: CaMg(CO3)2. Crystal structure: hexagonal (rhombohedral) ...
and silicides can be prepared in a similar way. Both the carbonate and sulfate are insoluble. Calcium salts impart a characteristic brick-red color to flames which is an aid to qualitative analysis. At ordinary temperatures calcium has the face-centered cubic structure with a transition at 450°...
A few calcium compounds, such as calcium oxide and calcium carbonate have been known since ancient times. The metal was isolated by Davy in 1808. Earlier its amalgam was prepared by Berzelius and Pontin. Calcium is the fifth most abundant element in the earth’s crust, constituting 4.15 % by...

Two types of calcium supplements are generally available – carbonate and citrate.Calcium carbonateis often considered the less expensive option; however, it must typically be taken with food.Calcium citrateis the more expensive option, but it is a higher quality supplement and may be taken on a...
Amorphous calcium carbonate is an important precursor for biomineralization in marine organisms. Key outstanding problems include understanding the structure of amorphous calcium carbonate and rationalizing its metastability as an amorphous phase. Here we report high-quality atomistic models of amorphous calcium...

the fifth most abundant element in the earth's crust (3.6 per cent), occurring esp as forms of calcium carbonate. It is an essential constituent of bones and teeth and is used as a deoxidizer in steel. Symbol: Ca; atomic no.: 20; atomic wt.: 40.078; valency: 2; relative density: ...
Alternatively, it may be obtained by treating calcium carbonate with hydrofluoric acid:CaCO3+ 2HF → CaF2+ CO2+ H2O. DefinitionA mineral form of calcium fluoride (CaF2), used in making some cements and types of glass. General DescriptionOdorless gray powder or granules. Sinks in water. ...
