Calcium Oxide (Quicklime) is a highly reactive, white, alkaline solid with the chemical formula CaO. Known for its strong caustic properties, it is produced by heating limestone in a kiln, driving off carbon dioxide to form quicklime. This versatile compound has been used since ancient times in construction, agriculture, metallurgy, and sanitation practices.
Due to its high reactivity with water, Calcium Oxide forms calcium hydroxide (slaked lime), releasing heat in the process. This makes it valuable in chemical manufacturing, water treatment, pH adjustment, and environmental remediation. Its ability to neutralize acids, remove impurities, and act as a fluxing agent has made it essential across diverse industrial sectors.
