What is Calcium Oxide?

Calcium oxide, commonly known as quicklime or burnt lime, is a chemical compound composed of calcium and oxygen. It is a white, crystalline solid with the chemical formula of CaO that is highly alkaline and reactive. Calcium oxide is produced by heating calcium carbonate (such as limestone) in a kiln, a process known as calcination.

Calcium oxide has a variety of uses in different industries. In construction, it is often used as a key ingredient in cement, contributing to its strength and durability. Calcium oxide can also be used in the production of lime mortar, which is used for bricklaying and plastering. In agriculture, calcium oxide can be applied to soil as a soil amendment to raise the pH level and reduce soil acidity. It helps neutralize acidic soils, promoting healthy plant growth.

Furthermore, it is employed in various industrial processes. Calcium oxide is used in the manufacturing of steel, where it helps remove impurities during the steelmaking process. It is also utilized in the production of glass, paper, and certain chemicals.

Properties of Calcium Oxide

Calcium oxide, also known as quicklime or burnt lime, has several notable properties:


It is highly reactive and readily reacts with water to form calcium hydroxide (slaked lime) through an exothermic reaction. This reaction generates heat and is commonly used for various applications, including in the production of heat and light.

Physical state

Calcium oxide is a white, crystalline solid at room temperature. It has a high melting point of approximately 2,572 degrees Celsius (4,662 degrees Fahrenheit).


It is strongly alkaline, meaning it has a high pH value. When dissolved in water, calcium oxide forms a basic solution due to the presence of hydroxide ions.

Desiccant properties

 Due to its ability to absorb moisture, calcium oxide is commonly used as a desiccant or drying agent. It can be employed to remove water from gases, liquids, and solids.

Hygroscopic nature

 It has a strong affinity for moisture and is hygroscopic, which means it readily absorbs water from the atmosphere. This property makes it useful for drying gases and materials.

Corrosive properties

Calcium oxide is corrosive to many materials, including metals. It can react with metals, such as aluminum and zinc, causing them to corrode or release flammable hydrogen gas.

Reactivity with acids

It reacts vigorously with acids, including dilute acids, to form calcium salts and water. This reaction is exothermic and can produce heat.

High density

Calcium oxide has a relatively high density, with a specific gravity of around 3.34 grams per cubic centimetre.

Low solubility

 It is sparingly soluble in water, with only a small amount dissolving to form calcium hydroxide.

Calcium Oxide Applications

Calcium oxide, or quicklime, has a wide range of applications across various industries due to its unique properties. Some of its key applications are:

  1. Waste treatment: It is utilized in waste treatment processes to treat and stabilize hazardous waste, including acidic or corrosive substances. Calcium oxide helps neutralize and immobilize the hazardous components, reducing their environmental impact.
  2. Construction: Calcium oxide is a crucial component in the production of cement. It reacts with water to form calcium hydroxide, which, when mixed with aggregates and other materials, creates a strong and durable binding agent for construction purposes. It is also used in the preparation of lime mortar, which is employed in bricklaying and plastering.
  3. Soil amendment: It is used in agriculture as a soil amendment to neutralize acidic soils. Calcium oxide helps raise the pH level, reducing soil acidity and creating a more favourable environment for plant growth. It also improves nutrient availability and enhances soil structure.
  4. Steel production: Calcium oxide is utilized in the steel industry during the steelmaking process. It helps remove impurities, such as silica and phosphorus, from the iron ore, facilitating the production of high-quality steel.
  5. Glass manufacturing: It is a significant ingredient in glass production and acts as a flux, lowering the melting point of the glass mixture and improving its workability. It also helps stabilize and strengthen the glass.
  6. Water treatment: Calcium oxide is employed in water treatment processes to adjust pH levels and remove impurities. It can be used to raise the pH of acidic water or as a coagulant to precipitate impurities for easier removal.
  7. Chemical industry: It serves as a precursor for various chemical compounds. It is used in the production of calcium-based chemicals, including calcium carbonate, calcium hydroxide, and calcium carbide, which have numerous applications in industries such as pharmaceuticals, food processing, and manufacturing.
  8. Desiccant: Calcium oxide’s hygroscopic nature makes it an effective desiccant or drying agent. It is used to remove moisture from gases, liquids, and solids, helping to preserve and protect sensitive materials.
  9. Animal feed supplement: It can be used as a calcium supplement in animal feed to ensure proper bone development and overall health in livestock.

These are just a few examples of the numerous applications of calcium oxide in various industries. Its versatile nature and reactivity make it a valuable compound with a wide range of uses.
