Calcium oxide (CaO), commonly known as quick lime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, quicklime specifically applies to the single chemical compound calcium oxide.
Calcium oxide that survives processing without reacting in building products such as cement is called free lime.Quicklime is relatively inexpensive. Both it and a chemical derivative (calcium hydroxide, of which quicklime is the base anhydride) are important commodity chemicals.
Importance of Calcium Oxide Powder : / Quick Lime
- The major use of Calcium Oxide is in the basic oxygen steelmaking (BOS) process.
- Ground quicklime is used in the production of aerated concrete blocks.
- Quicklime and hydrated lime can considerably increase the load carrying capacity of clay-containing soils.
- Calcium oxide is a key ingredient for the process of making cement.
- Calcium oxide is used to regenerate sodium hydroxide from sodium carbonate in the chemical recovery at Kraft pulp mills.
