Calcium carbonate is a white, odorless powder, or crystalline solid. 6.1 Uses Source of lime; neutralizing agent, filler, and extender in rubber, plastics, paints; opacifying agent in paper; fortification of bread; putty; tooth pow- ders; antacid; whitewash; Portland cement; sulfur dioxide remo...
The meaning of CALCIUM CARBONATE is a compound CaCO3 found in nature as calcite and aragonite and in plant ashes, bones, and shells and used especially in making lime and Portland cement and as a gastric antacid.
calcium carbonate: A white solid,CaCO3, which is only sparingly solublein water. Calcium carbonatedecomposes on heating to give calciumoxide (quicklime) and carbondioxide. It occurs naturally as theminerals calcite (rhombohedral; r.d.2.71) and aragonite (rhombic; r.d.2.93). Rocks containing cal...
In the construction industry, calcium carbonate is used as a raw material to produce lime cement and burnt lime or even as a solid block. In coal-fired power plants, it is used for flue gas desulphurisation and as a basic material for plaster production. Moreover, calcium carbonate is ...
precipitate in six solid modifications: three hydrated forms (amorphous calcium carbonate, calcium carbonate hexahydrate, calcium carbonate monohydrate) and three anhydrous polymorphs (calcite, aragonite and vaterite). Natural GCC is mostly calcite. Each of the ...
