CaO Quicklime: Uses, Benefits & Industrial Applications Explained
CaO Quicklime: Uses, Benefits & Industrial Applications Explained

Calcium oxide (CaO), also known as quicklime, is one of the most widely used industrial materials in the world. Without this material, a variety of procedures ranging from steel manufacturing and construction to environmental management and water treatment will be disrupted. Such a huge dependence on this material is a result of its strong alkalinity, high reactivity, and ability to neutralize impurities. These properties of this material explain the benefits of quicklime in industry, along with its applications that industrial users should know about.

What Are the Characteristics of Quicklime?

Quicklime is a white, grayish-white, or off-white alkaline material produced by heating limestone at temperatures generally above 900°C. The following are its key characteristics that you must know about when buying this important material from the best quick lime manufacturers in Rajasthan.

  • Produced from limestone through calcination
  • Strongly alkaline in nature
  • Reacts exothermically with water
  • Very high melting point
  • Impurity-removal capability
  • Absorbs moisture from the air
