What is Calcium Oxide? - Definition from …

Calcium oxide, commonly known as lime, has the chemical formula CaO. Hydrated lime is called calcium hydroxide, Ca(OH) 2, which is the cement in concrete. Calcium oxide has an adhesive property with bricks and stones, so it is used as a binding material in masonry works.

Oxide - Wikipedia

2019-4-22 · An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygen atom and one other element[1] in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth''s crust consists of solid oxides, the result of

A large amount of calcium oxide also is used as starting material in the production of calcium carbide, CaC 2, also known simply as carbide, or calcium acetylide. Colourless when pure (though technical grades are typically grayish brown), this solid decomposes in water, forming flammable acetylene gas and calcium hydroxide, Ca(OH) 2.
