Calcium Oxide (CaO) is cubic crystalline solid (I think it's face centered cubic but need to check on that). It's mainly used in the production of cement.
Calcium oxide is used to make paper, pottery, food, and to purify water (make it good to drink.) Calcium carbonate is used as a calcium supplement. Calcium permanganate can be used as a rocket propellant.
Calcium carbide also is used to make calcium cyanamide, CaCN 2, a fertilizer component and starting material for certain plastic resins. Calcium hydroxide, also called slaked lime, Ca(OH) 2, is obtained by the action of water on calcium oxide.

• Ten things you didn't know about Wikipedia • Oxide From Wikipedia, the free encyclopedia Jump to: navigation, search An oxide is a chemical compound containing an oxygen atom and other elements. Most of the earth's crust consists of oxides. Oxides result when elements are oxidized by air.
Calcium hydroxide, also known by the names slaked lime and hydrated lime, is an inorganic compound with chemical formula Ca(OH). It serves as an intermediate amongst basic calcium compounds, as it can be converted to both calcium oxide or calcium carbonate with relative ease.
Calcium aluminate of this structure is fairly rich in calcium oxide and has a comparatively low melting point (~1455[degrees]C); this is likely to account for its fragmentation into strings during cooling after an extensive elongation during hot rolling.
Calcium oxide (CaO), commonly known as burnt lime, lime or quicklime, is a widely used chemical compound. It is a white, caustic and alkaline crystalline solid. As a commercial product, lime often also contains magnesium oxide, silicon oxide and smaller amounts of aluminium oxide and iron oxide.
Residues of calcium oxide are exempted from the requirement of a tolerance when used in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or …
Large quantities of CO2 are produced by lime kilns, which burn limestone (primarily calcium carbonate) to produce calcium oxide (lime, used to make cement); and in the production of magnesium from dolomite (calcium magnesium carbonate).

Protein-bound calcium accounts for about 47 per cent of the calcium in plasma; most of it in this form is bound to albumin. Another 47 per cent of plasma calcium is ionized. About 6 per cent is complexed with phosphate, citrate, and other anions.
Calcium oxide is widely used in industry, e.g., in making porcelain and glass; in purifying sugar; in preparing bleaching powder bleaching powder, white or nearly white powder that is usually a mixture of calcium chloride hypochlorite, CaCl(OCl); calcium hypochlorite, Ca(OCl) 2; and calcium chloride, CaCl 2.
Calcium - Wikipedia, the free encyclopedia. ... Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide.
Calcium oxide is a chemical compound of calcium and oxygen. Its chemical formula is CaO. It is known as quicklime. It is made in a lime kiln. It releases heat when dissolved in water and changes into calcium hydroxide. It is a white powder. It is also a base. It reacts with acids to make calcium salts.
The intestine absorbs about one-third of calcium eaten as the free ion, and plasma calcium level is then regulated by the kidneys. Parathyroid hormone and vitamin D promote the formation of bone by allowing and enhancing the deposition of calcium ions there, allowing rapid bone turnover without affecting bone mass or mineral content.
Calcium oxide (CaO), commonly known as quicklime, is a widely used chemical compound. It is a white, caustic and alkaline crystalline solid at room temperature. As a commercial product, lime often also contains magnesium oxide, silicon oxide and smaller amounts of aluminium oxide and iron oxide.
Calcium (Latin calx, meaning "limestone") was known as early as the first century when the Ancient Romans prepared lime as calcium oxide. It was not isolated until 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
Calcium oxide is a basic anhydride, reacting with water to form calcium hydroxide; during the reaction (slaking) much heat is given off and the solid nearly doubles its volume. Cite this article Pick a style below, and copy the text for your bibliography.
