氧化钙 Calcium oxide
（重定向自Calcia）
氧化钙，俗称生石灰或石灰，化学式CaO，是常见的无机化合物。氧化钙通常从石灰石或贝壳获取，将含有碳酸钙的物质加热至500–600℃，使它分解成氧化钙和二氧化碳。这是少数史前已为人所知的化学反应。

Calcium oxide 氧化钙
（重定向自Calcia）
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, aluminium, and iron predominate. By contrast, "quicklime" specifically applies to the single chemical compound calcium oxide. Calcium oxide which survives processing without reacting in building products such as cement is called free lime.
