Calcium oxide powder
Description
Calcium oxide powder, commonly known as quicklime, is a white, caustic, alkaline solid (CaO) produced by calcining limestone at high temperatures.
Properties
It appears as a fine, odorless powder with high reactivity, density of 3.34 g/cm³, and melting point around 2572°C; it reacts exothermically with water to form calcium hydroxide (slaked lime) and is soluble in acids but not in water.
Production
Obtained by thermal decomposition of calcium carbonate (CaCO₃ → CaO + CO₂) in lime kilns at 900–1200°C, with the powder form achieved through crushing and grinding post-calcination.
Main uses
Widely employed in construction (mortar, cement), steel manufacturing (flux), water treatment (pH adjustment), agriculture (soil stabilization), and chemical processes as a desiccant or precipitant.
