Calcium Oxide - History’s versatile chemical - WorldOfChemicals

Why Calcium Oxide is known as a versatile chemical?

Calcium Oxide

Calcium oxide (CaO) known as a versatile chemical is a frequently used industrial compound. It’s a major and essential commodity chemical in industries like steelmaking and aerated concrete production since it is very cost-effective. However, Calcium oxide’s versatility has made it most demanded an industrial compound, and is as well responsible for making it one of the most versatile chemicals in history.

Generally, calcium oxide is referred to as quicklime or burnt lime. It possesses a property of white crystalline solid at room temperature, and it is also highly caustic. Quicklime is a vital constituent in a diversity of simple processes incorporating in cement-making, steelmaking, glass production, paper production, and even desulfurization. Since CaO is so naturally reactive, it’s frequently used as a detection compound in the ever-expanding industry of petroleum.

Versatile Characteristics of Calcium Oxide

1. When calcium oxide is heated, it releases an intense glow. This kind of illumination is known as limelight, and was used mostly used in theatrical productions prior to the invention of electric lighting.

2. Calcium oxide is used as a vital ingredient in cement manufacturing.

3. Calcium oxide is exploited to regenerate sodium hydroxide from sodium carbonate in the chemical recovery at Kraft pulp mills.

4. About 50% of calcium oxide is production is converted to calcium hydroxide prior to usage, and then used in the drinking water treatment.

5. Quicklime is also noted to have been a factor of Greek fire. When contact with water, quicklime would augment to the temperature above 150 °C leading to catch fire.


History of Calcium Oxide

Calcium Oxide is formerly derived from the thermal breakdown of limestone, at times mixed with water, CaO forms a viscous slurry material useful for a range of lime-based mortar applications.

Once quicklime is mixed with water, it turns into a spreading heat source. It also generates incandescent beams of light which are made up of oxygen and hydrogen when heated. This turns it into a viable light source for theatrical productions in ancient days.

Preparation of Calcium Oxide

Calcination is a method that is used to prepare burnt lime. It is a process which begins with thermally decomposing the reactants at high temperatures by making certain that the temperature is maintained under the melting point.

Calcium carbonate undertakes calcination at a temperature which ranges between 1070oC-1270oC, these makers the compound a versatile in nature. The chemical reactions are held in a rotary kiln. The products formed due to the reaction are burnt lime and carbon dioxide. The carbon dioxide produced is separated instantly so that the reaction is held until the completion of the process. uses cookies to ensure that we give you the best experience on our website.
