CALCIUM OXIDE – HIGH REACTIVITY QUICKLIME
Calcium-Oxide
Calcium oxide (CaO), commonly known as Quicklime, is a highly reactive alkaline material produced by the thermal decomposition of limestone (CaCO₃) at high temperatures.Calcium oxide ( ), or quicklime, is a white, caustic, and alkaline crystalline solid produced by heating limestone ( ) to ~900°C. Commonly used in construction (cement), steel manufacturing, and water treatment, it is a key industrial commodity. It reacts eagerly with water to produce heat and calcium hydroxide,
- Chemical Formula: CaO
- Appearance: White to off-white granular or lump
- Reactivity: Rapid exothermic reaction with water
- High Purity: Available in different grades
- Strong Alkalinity: pH > 12 when hydrated
Reaction with Water
Quicklime reacts vigorously with water to form calcium hydroxide: CaO + H₂O → Ca(OH)₂ + Heat This reaction releases significant heat and is essential in many industrial processes.
Hazards: It is a caustic substance that can cause severe skin irritation, eye damage, and breathing issues upon inhalation. It can generate intense heat when reacting with water.
