Quick lime

Quicklime, also known as burnt lime or calcium oxide (CaO), is a highly reactive chemical compound derived from heating limestone or other forms of calcium carbonate in a kiln. It is called "quicklime" due to its rapid and exothermic reaction with water, producing heat and converting into slaked lime or calcium hydroxide.

Quicklime has been used for various purposes throughout history, particularly in construction, agriculture, and industrial applications. In construction, quicklime is a key ingredient in the production of lime-based mortars, plasters, and stuccos. When water is added to quicklime, it undergoes a process called slaking, releasing a significant amount of heat and forming a white, powdery substance known as slaked lime. This slaked lime can be further processed to create lime putty, lime wash, or lime-based paints.

The reactivity of quicklime with water is utilized in several other industries as well. It is commonly used in water treatment processes to adjust pH levels and remove impurities. Quicklime is also employed in the steel and iron manufacturing industry as a flux agent, helping to remove impurities from the molten metal. Additionally, it plays a role in the production of chemicals, paper, and various other industrial processes.

It is important to handle quicklime with caution as it is caustic and can cause severe burns if it comes into contact with skin or eyes. Due to its reactivity and potential hazards, proper safety measures must be taken when working with quicklime.

Overall, quicklime is a versatile and widely used chemical compound with various applications in construction, industry, and agriculture. Its reactivity with water makes it a valuable component in the production of lime-based materials and facilitates its use in a range of industrial processes.
