Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used
chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature.
The broadly used term lime connotes calcium-containing inorganic materials, in which
carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminum, and iron
predominate. By contrast, quicklime specifically applies to the single chemical compound
calcium oxide.
