metal and occurs in minerals such as limestone and gypsum. It is a basic component of leaves, bones, teeth, and shells, and is essential for the normal growth and development of most animals and plants. Calcium is used to make plaster, cement, and alloys.Atomic number20. SeePeriodic Table...
calcium oxide [′kal·se·əm ′äk‚sīd] (inorganic chemistry) CaO A caustic white solid sparingly soluble in water; the commercial form is prepared by roasting calcium carbonate limestone in kilns until all the carbon dioxide is driven off; used as a refractory, in pulp and paper man...
Following power generation, cement stands as the second-largest industrial source of anthropogenic greenhouse gas emissions. However, in this invention a new molten salt chemistry now enables solar thermal energy to drive to calcium oxide production, completely eliminating carbon dioxide emissions during ...

calcium carbonate n. A colorless or white crystalline compound, CaCO3, occurring naturally as chalk, limestone, marble, and other forms and used in a wide variety of manufactured products including commercial chalk, Portland cement, medicines, and dentifrices.

aSUBSTANCE: lightened grouting material includes Portland cement clinker, fuel fly ash and siliceous additive, at least, one from group including tripoli, opoka, diatomite, gypsum and calcium chloride. In this case, Portland cement clinker has free calcium oxide within 0.5-3.0 wt.%. Fuel fly ash...
Tetracalcium phosphate is obtained by reacting calcium hydrogenphosphate and calcium carbonate, derived from organic component-free alga indurated fabric at 1400 deg C, cooling in the absence of water and granulating. Independent claims are included for: (1) a bone cement powder produced by reacting...
