quicklime

Quicklime, chemically known as calcium oxide (CaO), is a widely used inorganic compound produced through the thermal decomposition of limestone (calcium carbonate, CaCO₃) in a process called calcination. This occurs in vertical shaft kilns or rotary kilns at temperatures exceeding 900°C. The resulting product is a white, caustic, crystalline solid that is highly reactive with water, producing slaked lime (calcium hydroxide) and significant heat. The global quicklime market is driven by its essential role in steel manufacturing, environmental applications (flue gas treatment and water purification), construction, and chemical processing. In 2025, the market was valued at approximately USD 45.8 billion, with a projected compound annual growth rate (CAGR) of 4.2% through 2032. Quicklime’s versatility makes it a cornerstone of industrial economies, particularly in regions with robust infrastructure and manufacturing sectors.
