Calcium oxide (Ca₂O), also known as quicklime or burnt lime, is an alkaline ceramic compound produced by thermal decomposition of limestone and widely used in construction, chemical processing, and metallurgy. This material is valued for its reactivity with water and CO₂, making it essential in cement production, steel refining, and environmental remediation applications where its high alkalinity and ability to absorb moisture are leveraged. Engineers select calcium oxide for processes requiring strong base chemistry and thermal stability, though its hygroscopic nature and caustic properties require careful handling in design specifications.
